GENERAL SAFETY RULES
There is a serious risk of personal injury if you do not follow all instructions laid
down in this guide.

3. Keep children, animals and bystanders away from the work area.
4. Never use this hoist if you are ill, feeling tired, or under the influence of
alcohol or drugs.
5. 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 hoist
should be removed from service and the parts renewed or repaired before
further use.

hard hat. Avoid loose garments and jewellery that could catch in moving
parts, tie back long hair
8. Protect the machine from extreme weather conditions, i.e. frost and/or
high temperatures.
9. The machine is equipped with a thermal cut-out. If the load exceeds the
capacity of the machine this will cause the motor to overheat and the
thermal cutout to activate, Let the hoist cool down before using it again.
10. Make sure the load is balanced, stable and that personnel stand clear of
the raised load.

beam/box section able to take the combined weight of the load and the
hoist.

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.
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 lead of this appliance may not correspond with the
coloured markings identifying terminals in your plug proceed as follows:
• Connect GREEN & YELLOW cord to terminal marked with a letter “E” or Earth
symbol “ ” or coloured GREEN or GREEN & YELLOW.
• Connect BROWN cord to terminal marked with a letter “L” or coloured RED.
• Connect BLUE cord to 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-
rewireable) 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. When replacing a detachable fuse carrier,ensure 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.
FUSE RATING
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.
We strongly recommend that this machine is connected to the mains supply via a
Residual Current Device (RCD)
If in any doubt, consult a qualified electrician. DO NOT attempt any repairs yourself.
