OPERATION
Before connecting the drop hammer to the carrier hydraulic
PRE-INSTALLATION INSTRUCTIONS
system; it is important to determine which are the pressure and
tank lines of the carrier and connect the hoses appropriately.
The pressure and tank lines are marked where they enter the
valve block. If the hydraulics are connected incorrectly, the
motor will rotate in the wrong direction. This will not damage
the machine but it will not lift.
SKIDSTEER, BACKHOE OR EXCAVATOR SIZE
Check the Specifications section of this manual to
determine correct carrier size, hydraulic flow and pressure
requirements.
If hydraulic pressure, hydraulic back-pressure,
hydraulic flow or excavator weight class are exceeded, the
drop hammer warranty is void.
TOOL INSTALLATION
WARNING
Do not lift or transport the drop hammer without the
travel lock installed.
Do not use bare hands to check or search for hydraulic
leaks around hoses and fittings. Pinhole leaks can
penetrate the skin. To inspect for leaks, depressurize
the system, clean around suspected area, repressurize
the system and visually check for leaks.
The hammer can move freely in the housing if the
travel lock is not installed which can result in serious
injury or death.
Ensure travel lock is installed.
TEST THE HYDRAULIC SYSTEM
The drop hammer may be lifted with a forklift through the
mounting bracket or by feeding chains through the points
shown in Figure 1 below. Always lift the drop hammer with
machinery and lifting equipment that is rated to carry the
weight of the machine.
1. Have your Stanley dealer test the carrier hydraulic
system to make sure the system is operating at the
manufacturers specified capacity and pressure ratings.
2. Be sure the fluid in the hydraulic system is clean.
3. Check the hydraulic filter. Replace the filter if dirty or
deteriorated.
4
Have your Stanley dealer test the circuit to which the
breaker will be connected to make sure that the circuit is
supplying the specified flow and pressure rating for the
breaker. See the Specifications section of this manual.

HYDRAULICS
Some carriers may have flows above or below flow and
pressure ranges required. Refer to Flow and Pressure
Specifications on page 17 of this manual. If the flow is lower
the drop hammer will simply cycle at a slower rate. If the flow
rate is higher the control valve on the drop hammer will limit
the flow to prevent the chain over-speeding and catching the
weight as it drops.

OPERATION
MOUNTING TO THE CARRIER
OPERATION
1. With the drop hammer laying on a flat level surface bolt the
mounting plate to the mounting bracket. Ensure these bolts
are torqued to the recommended value.
NOTICE
2. Bring the carrier up to the drop hammer from the bottom or
impact end. If you have a quick attachment systems maneuver
the mount plate on the carrier until it engages with the adaption
plate. Then actuate the slides or levers to lock the plates
together. With a pin mount system; maneuver the carrier until
the pinholes are aligned and slide in the connection pins.
Failure to remove the travel lock may result in damage
to the equipment during operation.
Ensure the pins are bolted in place. Grease these pivots as per
the carrier manufactures recommendations. Never operate
the drop hammer with a loose or ill-fitting attachment.
Exposure to silica dust during construction activities
can cause serious or fatal respiratory disease. Use
adequate respiratory protection.
Connect the hoses to supply oil to the port marked "PRESS"
on the valve block.
3. Carefully raise the drop hammer to the vertical position
keeping the base of the machine close to the ground
throughout the lifting movement. Slowly move the Cyclone
through the full extent of rotation and lift to ensure no part of
the machine or any hydraulic hosing foul the carrier arms or
cylinders. Ensure hoses are long enough so they do not pull
tight in any part of the rotation and short enough to stay clear
of the ground or operating area.
4. Once the drop hammer is securely mounted to the carrier
the Traveling Lock may be removed. Be sure to store this
plate safely for future use.
OPERATION
During use, the traveling lock may be bolted outside the
housing using the same hole as shown in Figure 2 below.
Ensure that the drop hammer is operated at a safe distance
from other personnel and equipment. Be sure all guards are
in place.
The drop hammer's weight is normally rested on the skids
during use. However when moving about the drop hammer
may represent a heavy load for the carrier. Therefore care
must be taken when moving about a job-site or when loading
or unloading from a transporter. The drop hammer should be
carried as low as possible and special care taken when nego-
tiating uneven surfaces. Know the limits of your carrier.
Traveling Lock
NOTICE
The drop hammer is intended for use only on level or near
level surfaces. Do not operate the drop hammer on uneven
or unlevel surfaces.

OPERATION
GENERAL TECHNIQUE FOR BREAKING SLAB
1. Tip the drop hammer to a horizontal position.
Rest the drop hammer in a vertical position on the concrete
to be broken. The skids should be just resting on the concrete
with some of the weight taken by the carrier. If a crack appears
in the top surface of the concrete you can be sure it is broken
all the way through.
2. Gradually move the drop hammer past horizontal until the
weight slides forward. This can be done in a controlled manner
by shaking the weight out using the curl lever.
3.Allow the Hammer to slide out until it hits against the Safety
Pin.
Actuate the hydraulics and the drop hammer will start to cycle.
As the concrete cracks or breaks move the carrier. It is best
to move while the hammer is raised and pause momentarily
as the hammer strikes.
4. Return the drop hammer to horizontal and rest it on the
ground and Shut the carrier off.
5. On the under-side of the Hammer remove the Bolt and Peg
Locking Plate that hold the Hammer Peg.
Generally all that is required is to hit the concrete until it cracks
and then move 6-12 inches /150-300 mm. Sitting in one place
will pulverize the concrete and eventually the hammer will hit
the column buffers. This is felt as a hard jarring action through
the machine.
6. Remove the Hammer Peg and replace it in the next hole.
Tighten to 180 ft/lbs/240 Nm for the DH3500 and DH9000,
for the DH1500 tighten to 140 ft lbs/190 Nm with the Bolt and
Peg Locking Plate. See Figure 3 below.
With skid steers movement can be in any direction but gener-
ally moving in a reverse direction provides the best control.
On excavators setting the machine down and moving in arc
with the slew drive is usually the quickest method.
Hammer Peg
Hex Head Setscrew
Peg Locking Plate
Hammer Safety Pin
It is important to keep the drop hammer as vertical as possible
during operation as this provides the greatest impact.
When breaking thinner concrete, the drop hammer may hit
too hard and punch completely through. In this instance the
hammer sticking into the concrete and stopping the carrier
traveling can slow production. If this occurs adjust the impact
of the drop hammer as described below.
Hammer
Figure 3. Hammer Adjustment
7. Restart the carrier and SLOWLY raise the drop hammer
until the Hammer slides down the column.
MAINTENANCE
It is recommended that only genuine Stanley parts are used.
Genuine Stanley drop hammer parts are all checked for
allowable tolerances.
Although the drop hammer is a simple machine, it is subject
to severe stresses and shocks during normal operation. A
five-minute daily check will ensure that your drop hammer
remains in good condition and will prevent unscheduled
down time.
ADJUSTING IMPACT
DAILY INSPECTION
Check that all the mount plate bolts that connect the drop
hammer to the carrier are tight and torqued to the recom-
mended value.
Check that the motor flange bolts are tight and secure.

tension. The chain should move about 1/2 inch/10-15 mm at
its center point. To adjust the chain, loosen the Tensioning
Bolt lock nuts (Item 32 DH1500 or Item 30 DH3500) and the
Clamp Nut (Items 41-42 DH1500 or Items 34-35 DH3500).
Adjust the Tension Bolts evenly (so that the lower shaft/
sprocket are kept parallel). See Figure 4 below.
It is worthwhile at this stage to dress the hammer tip and
remove any excessive burring.
