TRACK LIMITED PRORATED
WARRANTY POLICY STATEMENT
Compact Power Inc provides a limited warranty to the original purchaser that the
original tracks used on consumer products sold by Compact Power or its authorized
Distributor/Dealer, and manufactured by its subsidiary Mertz Mfg., will be free from
defects in material and workmanship for a period of one (1) year after the date of
purchase or 400 hours of use, whichever occurs first. Compact Power or its
authorized Distributor/Dealer will replace any track found to be defective in either
material or workmanship, using the below described prorated discount structure, and
subject to the conditions, limitations, and exclusions set forth herein.
The one year or 400 hours of use duration of this warranty applies only if the product
is put to ordinary and reasonable use.
Genuine manufacturer supplied replacement track(s) not purchased with the original
product purchase, but which are later purchased and used with that product, are
warranted to be free from defects in material and workmanship for a period of sixty
(60) days after the date of the “parts” purchase or 100 hours of use. The purchaser of
these replacement tracks must be able to document the time frame and hours of use
for the replacement tracks. Compact Power or its authorized Distributor/Dealer will
repair or replace any such track free of charge during that period.
Prorated discount structure: If the original track becomes unserviceable within the
first 100 hours of use, Compact Power or its authorized Distributor/Dealer will
replace that track at no cost including replacement labor. If the original track
becomes unserviceable within the first 200 hours of use, Compact Power or its
authorized Distributor/Dealer will replace the track with a prorated discount from the
cost of the track and no charge for the replacement labor. If the track becomes
unserviceable within the first 400 hours of use, Compact Power or its authorized
Distributor/Dealer will replace the track with a prorated discount from the cost of the
track with no replacement labor paid.
This warranty is subject to the following conditions, limitations,
and exclusions:
This warranty is valid only if the following conditions are met:
The warranty registration card must be completed and returned to manufacturer of the
product.
The purchaser must perform maintenance and minor adjustments explained in the
owner's manual.

Warranty service must be performed by Compact Power or its authorized Dealer's
service representative
The following items are not covered by this Track Limited Warranty:
Parts that are not genuine original manufacturer service parts are not covered by this
warranty.
Products which are damaged and sold as salvage units or in an “as is” condition are not
covered by this warranty.
Any defect which is the result of misuse, alteration, improper assembly, improper
adjustment, neglect, accident, or damage caused by natural calamity beyond human
control such as fire, flood, etc. is not covered by this warranty.
EXAMPLE OF THE 'PRORATED' COMPUTATIONS OF THIS TRACK
LIMITED WARRANTY:
First, divide the number of hours on the original tracks, the hours on the unit, by 400
to determine the “wear percentage factor.” Next, subtract the result from 1 to
determine the “prorated discount” to be applied to the cost of the track.
If a unit has 150 hours and requires a new track; divide 150 by 400 which equals .38,
the “wear percentage factor.” Subtract that number from 1 which equals .62, or 62%,
the “prorated discount.” In this case, the dealer will receive a warranty credit in the
amount of his cost for the track less 62%. If the hours are less that 200 on the original
track, a labor allowance of ½ hour will also be credited. No replacement labor will be
paid if hours are over 200.
LIMITATION OF REMEDY AND DAMAGES
Compact Powers liability under this warranty, and under any implied warranty that
may exist, is limited to repair of any defect in workmanship, and repair or
replacement of any defective part. Compact Power shall not be liable for incidental,
special, or consequential damages (including lost profits). Some states do not allow
the exclusion of incidental or consequential damages, so the above limitation or
exclusion may not apply to you.
DISCLAIMER OF FURTHER WARRANTY
Compact Power makes no warranty, express or implied, other than what is
expressly made in this warranty. If the law of your state provides that an implied
warranty of merchantability, or an implied warranty of fitness for particular
purpose, or any other implied warranty, applies to Compact Power, then any
such implied warranty is limited to the duration of this warranty. Some states do
not allow limitations on how long an implied warranty lasts, so the above
limitation may not apply to you. This warranty gives you specific legal rights,
and you may also have other rights which vary from state to state.

operate the machine until all required repairs have been made.
• If the unit must be left unattended, shut the machine down and make sure that it can not be
started by an unauthorized individual.
• Operating on steep slopes can be dangerous and there is a greater risk of the machine tipping
over or becoming unstable. The list of rules below must be understood and followed for
maximum safety:
– Avoid excessively steep slopes or unstable surfaces. If travel on a slope is necessary, keep
the load low and proceed with extreme caution.
– DO NOT travel ACROSS excessively steep slopes under any circumstances.
– Travel straight up and down slopes with the heavy end of the machine pointing up the
incline. When the machine has no load, the operator's platform end of the machine is
considered the heavy end.
– Turning on slopes is not a recommended practice, however if you must turn on slopes;
reduce travel speed to as slow as possible, and exercise extreme caution. Avoid sharp turns
or sudden movements.
– Wet or slick ground conditions should be avoided as reduced traction could cause the
machine to slide down the slope.
– Never park the unit on a slope.

Safety Precautions
Battery Hazards
Before working with batteries, the following are important points about battery safety that you
should be aware of:
• Batteries are always surrounded by extremely explosive gases. This is especially true when
the battery is being charged. To avoid explosion:
– Do not smoke near batteries.
– Keep arcs, sparks and open flames away from batteries.
– Perform battery service work only in a well ventilated area.
• Make sure to dispose of batteries according to local regulations.
• Electrolyte Hazards:
NOTICE
The batteries on the machine may be either be “wet cell” or gel cell.
It is still important to know and follow these warnings and cautions.
• Battery electrolyte in standard “wet cell” batteries contains sulfuric acid which is poisonous
and can cause severe chemical burns. To avoid personal injury:
– Wear a face shield to prevent sulfuric acid contact with your eyes
– Wear chemical resistant gloves and clothing to keep acid off your skin and clothing.
– Since wet cell batteries give off explosive gases, use a flashlight to check the electrolyte
level, not an open flame such as a match.
– Never check the battery by placing a metal object across the battery posts. The resulting
spark could ignite anything flammable, causing fire or an explosion.
– If electrolyte is splashed into your eyes, flush them immediately with clean water and seek
medical attention.
– If electrolyte is swallowed, seek medical attention immediately.
– If electrolyte is splashed onto exposed skin or clothing, flush and clean the area
immediately with clean water and seek medical attention if necessary.
Jump Starting/Battery Charging Hazards
Follow the instructions for jump starting or battery charging in the engine owner's manual. You
must be at the operator's platform when attempting to start the unit with booster batteries and
jumper cables so that you are at the controls when the engine starts.
Here are some general safety rules you must follow for jump starting the machine:
• Make sure to connect the positive jumper cable to the positive (RED) terminal on the battery.
• Connect the negative cable to the engine, machine chassis or the furthest ground point away
from the battery. Never make the final connection at the starter or dead battery. Sparks may
ignite the explosive gases surrounding the battery.
• When disconnecting cables after jump starting, remove the negative cable first and then the
positive cable.IMPORTANT: DO NOT let the cable clamps touch when disconnecting them.
• Severe damage can occur to the booster battery or machine.
• Never charge a battery or attempt to jump start a frozen battery. The sudden surge in
electrical power could cause the battery to explode.

Safety Precautions
Hydraulic System Hazards
The hydraulic system is under pressure whenever the engine is running and may hold pressure
even after the engine is shut off. Cycle all hydraulic controls after the trench boom is resting on
the ground. Some components will retain residual or trapped pressure. Use extreme caution
when removing any hydraulic component.
During inspection of the hydraulic system:
• Cycle all hydraulic controls to release residual pressure.
• Wait for the hydraulic fluid to cool down before disconnecting any hydraulic lines. Hot
hydraulic fluid can cause severe burns.
WARNING
Hydraulic oil under pressure can penetrate body tissue causing serious injury and
possible death. When troubleshooting a hydraulic system for leaks, always use cardboard
or wood as a detector. DO NOT USE YOUR BARE HANDS. If you are injected with
hydraulic oil or any other fluids, immediately seek treatment by a doctor trained in the
treatment of penetrating fluid injuries.
• Hydraulic fluid can cause permanent eye injury. Wear safety glasses or a full face shield to
provide appropriate eye protection.
• When venting or filling the hydraulic system, loosen the filler cap slowly to allow any
pressure in the hydraulic tank to be released and remove the cap gradually.

Safety Precautions
Fueling Hazards
Most fuels are highly flammable. Observe the following precautionary practices to reduce the
possibility of a serious accident:
• Always refuel the unit in an open, well ventilated area away from sparks or open flames.
DANGER
Gasoline Engines:
• Shut the engine off before attempting to fuel the machine. Never refuel a unit while
it is running.
• Allow engine to cool before re-fueling
• Always use a funnel or pour spout when filling the tanks.
• Under certain circumstances a static charge can develop and ignite the fuel. Make
sure that you are standing on the ground when filling the fuel tanks.
• If you are filling the fuel tanks from a service vehicle, make sure to connect the
service vehicles ground cable to the machine before beginning the fueling process.
• Keep the fuel nozzle in constant contact with the rim of the machines fuel tank.
• When filling a portable gas container, always place it on the ground. Never fill a
portable fuel container while it is inside a vehicle, truck, pick-up bed, or any
surface.
• To avoid static sparks when using a portable fuel container, only fill the container
when it is positioned on the ground and keep the fuel container nozzle in contact
with the tank opening during filling.
• Make sure to move the unit from the transport truck or trailer and only refuel the
unit on the ground, using an approved container.
• Keep sparks and flames away from fuel.
• Do not smoke while refueling or when handling the fuel container.
• Never cut or weld on or near fuel lines, tanks or containers.
• Never overfill the tank.
• Clean up spilled fuel immediately.

Machine Travel Controls
WARNING
• Levers and controls should return to the neutral position when they are released.
• Make sure that all of the controls are in the neutral (middle) position before starting the
engine.
• Operate the controls gradually and smoothly. Excessive speed and quick control movements
without regard for working conditions could cause an unsafe situation.
• Make sure to maintain your grip on both of the hand grips any time the machine is in motion.
NOTICE
Due to the spring tension system built into the track drive system as a safety mechanism, the
machine can be put into an extreme situation during which the drive sprocket will
bypass the rubber track guide holes causing a popping noise, called “cogging”.
This situation is part of the track drive systems safety design, and indicates
that this portion of the safety system is functioning properly.
3-10
Download from Www.Somanuals.com. All Manuals Search And Download.
Pre-Start Inspection and Operation
The “cogging” condition is most likely to occur while operating in a forward direction pulling a
heavy load, and during the first 50 hours of track usage. It is caused by the tension spring being
fully compressed due to high track load. If a cogging condition occurs, immediately stop
machine travel and machine functions and reverse travel direction slightly to de-compress track
tension. Continued cogging will cause the track drive sprocket to seat into the rubber track
incorrectly, and cause damage to the track. If cogging occurs, stop travel function and check for
and remove any debris or foreign matter in the drive system, check track for proper tension as
shown in Section 4 of this manual, and resume operation.

Chain Configuration
You can set up the chain in different configurations, depending on the width of the trench
desired and the soil conditions at the work site. Depending on the size of boom you purchased,
you will either have a chain with:
• 24 links (24 inch [60.9 cm] boom)
• 32 links (36 inch [91.4 cm] boom)
Each link can have digging teeth fastened to it and are referred to as a station. At any station,
the teeth can be fastened in various configurations with spacers and tubes to vary the width of
cut. The station configurations are placed along the chain in an order that maximizes digging
efficiency.
There are two types of teeth, cupped and triangular rock teeth. Cupped teeth are designed to cut
through and remove soil. Triangular rock teeth cut rock and other hard ground. The teeth are
cupped or angled differently depending on which side of the chain they are intended to be
fastened (i.e., either left or right). The teeth are fastened to the chain links using bolts, nuts,
tooth configurations.
The table on the following page lists some of the chain configurations, detailing which tooth
configuration should be installed at each station around the chain for each chain configuration.
NOTICE
Each table lists the configurations for 32 positions. If you are changing the configuration of a
24 link chain, ignore the positions 25 through 32 in the tables.
