SAFETY PRECAUTIONS
1. This machine is designed for indoor, domestic use. Do not use outdoors unless
it is completely protected against the elements.

temperatures.
5. The machine is not equipped with an overload cut-out. If the load exceeds
the capacity of the machine, do not persist in pushing the hoist button as this
will cause the motor to overheat and eventually damage will be inccurred.
6. NEVER stand beneath a raised load.
7. Before operating it is important to ensure that the steel cable is correctly wound
around the drum - see fig. 3, page 4.
8. Before operating ensure that at least THREE turns of the cable are wound
around the drum.
9. If the cable needs replacing, ensure it is replaced with one of identical
specification. Contact your CLARKE dealer or the CLARKE International Service
Department for advice.
10. Ensure that the switches are kept in good condition.
11. Before use, always inspect the machine and its’ mountings to ensure they are
in good condition. If any damaged or broken parts are found, the machine should
be removed from service and the parts renewed or repaired before further use.

Wiring Diagram
ELECTRICAL CONNECTIONS
Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply through an
approved 13 amp BS 1363 plug, or a suitably fused isolator switch.
WARNING! THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in the mains lead are coloured in accordance with the following
code: Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colours of the flexible cord of this appliance may not correspond with the coloured
markings identifying terminals in your plug proceed as follows:
Connect GREEN & YELLOW coloured cord to plug terminal marked with a letter “E”
or Earth symbol “ ” or coloured GREEN or GREEN & YELLOW.
Connect BROWN cord to plug terminal marked with a letter “L” or coloured RED.
Connect BLUE cord to plug terminal marked with a letter “N” or coloured BLACK.
If this appliance is fitted with a plug which is moulded onto the electric cable (i.e. non-
rewirable) please note:
1. The plug must be thrown away if it is cut from the electric cable. There is a danger of
electric shock if it is subsequently inserted into a socket outlet.

2. Never use the plug without the fuse
cover fitted.
3. Should you wish to replace a detach-
able fuse carrier, ensure that the
correct replacement is used (as
indicated by marking or colour
code).
4. Replacement fuse covers can
be obtained from your local
dealer or most electrical stockists.
5. The fuse in the plug must be replaced with one of the same rating (13 amps) and
this replacement must be ASTA approved to BS1362
INSTALLATION
The Hoist is provided with a specially designed brackets allowing it to be attached to
pipes, box sections or rectangular beams. (see fig. 1)
Beam dimensions must be carefully
calculated and all mountings must be of
adequate size and capable of sustaining the
maximum load of the hoist, plus the weight of
the hoist and mountings.
If there is any uncertainty. You should consult
a qualified engineer.

When lowering a load, be aware that when the hoist button is released, the load will not
stop immediately, but may continue for a few more millimeters as the brake takes effect
It is possible to double the capacity of the hoist by doubling the cable about the pulley,
and attaching the hook to the hoist casing via the hole provided.(see fig. 2)
Fig.3.
OPERATION
Taking all necessary precautions
previously stated, pay out the cable,
under tension so that the coils on the
drum remain neatly in place. Attach
the hook to the load, ensuring it is
directly above the centre of gravity of
the load, or in a direct line with the
winch.
Ensuring that no obstacle prevents a
clean lift or pull, gently raise the load
or winch ‘in’.

MAINTENANCE
Before use, check to ensure the motor stop switch and push button switch are in good
condition.
Periodically, fully unwind the cable and check its general condition, for fraying, corrosion
etc.
Periodically check the security and condition of the mountings and brackets.
Periodically check the tightness of all bolts and screws.
NOTE: When in constant use, the hoist should be inspected more frequently - at least
monthly.
IMPORTANT
These machines have been tested to a safety factor of 1.25.
Following repairs or disassembly, they must be re-tested with a static load of
315kg (CHP250) or 500kg (CHP400), in double wire mode.
There must be no failure or deformity of any kind incurred.
