• Do not use your tool where there is a risk of causing a fire or an explosion; e.g. in the
presence of flammable liquids, gasses, or dust. Power tools create sparks, which may ignite the
dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you
to lose control, so visitors should remain at a safe distance from the work area.
• Be aware of all power lines, electrical circuits, water pipes and other mechanical hazards in
your work area, particularly those hazards below the work surface hidden from the operator’s
view that may be unintentionally contacted and may cause personal harm or property damage.
• Be alert of your surroundings. Using power tools in confined work areas may put you
dangerously close to cutting tools and rotating parts.
ELECTRICAL SAFETY
•
WARNING! Always check to ensure the power supply corresponds to the voltage on
the rating plate.
• Do not abuse the cord. Never carry a portable tool by its power cord, or yank tool or extension
cords from the receptacle. Keep power and extension cords away from heat, oil, sharp edges or
moving parts. Replace damaged cords immediately. Damaged cords may cause a fire and
increase the risk of electric shock.
• Grounded tools must be plugged into an outlet properly installed and grounded in accordance
with all codes and ordinances. Never remove the grounding prong or modify the plug in any way.
Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to
whether the outlet is properly grounded.
• Double insulated tools are equipped with a polarized plug (one blade is wider than the other).
This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet,
reverse the plug. If it still doesn’t fit, contact a qualified electrician to install a polarized outlet. Do
not change the plug in any way.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators.
There is an increase risk of electric shock if your body is grounded.
• When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.”
These cords are rated for outdoor use and reduce the risk of electric shock.
• Extension Cord Use.
A. Use only ‘Listed’ extension cords. If used outdoors, they must be marked “For Outdoor Use.”
Those cords having 3-prong grounding type plugs and mating receptacles are to be used
with grounded tools.
B. Replace damaged or worn cords immediately.
C. Check the name plate rating of your tool. Use of improper size or gauge of extension cord
may cause unsafe or inefficient operation of your tool. Be sure your extension cord is rated
to allow sufficient current flow to the motor. For the proper wire gauge for your tool, see
chart.

• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
• Do not let your fingers touch the terminals of plug when installing to or removing from the
outlet.
• Ground fault circuit interrupters. If work area is not equipped with a permanently installed
Ground Fault Circuit Interrupter outlet (GFCI), use a plug-in GFCI between power tool or
extension cord and power receptacle.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught
in moving parts. Air vents often cover moving parts and should be avoided.
• Use safety apparel and equipment. Use safety goggles or safety glasses with side shields
which comply with current national standards, or when needed, a face shield. Use as dust mask
in dusty work conditions. This applies to all persons in the work area. Also use non-skid safety
shoes, hardhat, gloves, dust collection systems, and hearing protection when appropriate.
• Avoid accidental starting. Do not carry the power tool with your finger on the switch. Ensure
the switch is in the off position before plugging tool into power outlet. In the event of a power
failure, while a tool is being used, turn the switch off to prevent surprise starting when power is
restored.
• Do not overreach. Keep proper footing and balance at all times.
• Remove adjusting keys or wrenches before connecting to the power supply or turning on the
tool. A wrench or key that is left attached to a rotating part of the tool may result in personal
injury.
TOOL USE AND CARE
• Do not force the tool. Tools do a better and safer job when used in the manner for which they
are designed. Plan your work, and use the correct tool for the job.
• Never use a tool with a malfunctioning switch. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired by an authorized service representative before using.
• Disconnect power from tool and place the switch in the locked or off position before servicing,
adjusting, installing accessories or attachments, or storing. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
• Secure work with clamps or a vise instead of your hand to hold work when practical. This safety
precaution allows for proper tool operation using both hands.
• Store idle tools. When tools are not is use, store them in a dry, secure place out of the reach of
children. Inspect tools for good working condition prior to storage and before re-use.
• Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may create a risk of injury when used on another
tool.
• Keep guards in place and in working order.
• Never leave tool running unattended.

• Do not exceed the maximum lift capacity. The application, size and type of load, the
attachments to be used and the period of use must be taken into account
.
• Do not stand under hoisted loads.
• If pushing the lift button continually does not have any affect, do not continue. This is a
sign that the load exceeds the maximum capacity.
• Never adjust the cable or work on the Hoist when it is plugged into an outlet.
• Always inspect the cable and hook prior to use. If he cable is damaged in any way, do not
use it. Hooks that are bent, worn or whose openings are enlarged beyond normal throat opening
should not be used.
• If the Hoist is stopped during the lowering of a load it is normal for the load to drop a few
inches more due to inertia.
• The Hoist motor does NOT have an overload cut-out. If you are unable to hoist a load and
the load is under the maximum lift capacity, stop the Hoist and allow the motor to cool down
before trying again.
• Make sure the cable is correctly wound around the wheel. See FIGURE 1 below.
• Do not support a load over or around people or animals.
• Do not leave load suspended in the air unattended.
• Do not allow a load to bear against the hook latch. Allowing a load to bear against the hook
latch can result in loss of load.
• Do not allow load to swing or twist while hoisting.
• Do not use cable as a sling or wrap cable around a load.
ASSEMBLY
The hoist can be used in the following ways:
1. Fixed on a 1-7/8" (48mm) pipe with fixing clamps
2. With sliding wheels and installed on a gantry complete with slide track supplied by the
manufacturer and fitted according to the user’s need with counterweight containers or clamps
for anchoring ( see paragraph below “installation with gantry”)
3. Fixed to a framework made by the user in compatibility with the sliding unit
The user, who shall be entirely responsible for the correct use of the hoist, must remember
the following instructions and provisions:
•
The load bearing structures built by the user must have sufficient stability and capacity to
resist the forces exerted by the hoist or its supports in a accordance with dimensions and
conditions of constraint, so that the stresses in these structures are kept within the
allowable limits established by the relevant standard for the various materials. In order to
allow the necessary calculations to be made, the following illustrations show the forces
exerted at the constraints for the various cases involved.

OPERATION
1. Before making the connection to the electric control panel, check that the line voltage
corresponds to that shown on the motor plate. In case of three-phase motor, check also the row
or triangle connection of each phase.
2. The user must provide the electrical connection to the hoist using insulated conductors of
adequate cross-section and a multiple socket fitted upstream with a suitable switch with
differential magneto-thermal relay to protect form over current and indirect contacts. Also check
that the ground terminal in the socket is actually connected to the grounding system.
3. The cross-section of the power supply cable must be sized according to its length.
4. At the time of installation, check so that when the hook descends to the endpoint of its travel, at
least three turns of rope remain wound on the drum. The rope must never be unwound further
that this. The unwinding limit is shown on the rope by a red mark.
5. Do not under any circumstances use the hoist for lifting loads in a non-vertical direction.
6. In order to stop the hoist when running, it is usually enough to release the push-button on the
remote. Should an EMERGNECY STOP be necessary, press the red stop button to stop
operation, or disconnect from power source immediately.
7. During operating, constantly check that the rope winds onto the drum correctly.
8. It is strictly forbidden to cause the load to fall in an uncontrolled manner.
9. At intervals of no more than 15 days, check:
a). All the nuts and bolts on the hoist and the support are tight
b). The support is perfectly horizontal; if not, re-adjust
c). The brake suspending the load works effectively. If necessary re-adjust as follows: remove
the motor casing by loosening the 4 self-tapping screws on the fan cover; adjust the air gap by
unlocking the hexagonal socket head screw “A” and turning the nut “B”; the distance “C” must
be between 0.4 and 0.6mm. While the motor is running, the fan “D” must turn freely without
rubbing against the disc. Check that the brake works correctly, then replace the casing and fix in
place with the screw.

10. Be sure to check the condition of the cable every three months, and replace it if the wires are
damaged, twisted, frayed or broken.
Consequently, if the cable needs to be replaced, it can be secured using U-bolt
clamps suitably proportioned to the diameter of the cable itself, as indicated in
the diagram.
Only during primary operation, the manufacturer shall use a special aluminum
coupling for the assembly. However, this requires the use of specific equipment.
As with all maintenance work, replacement of the cable and the relative clamps
must be carried out by specialized personnel.
