CAUTIONS IN OPERATION AND MAINTENANCE
An electric hoist has been used as a safe and convenient machine to save time and labor in
operation. Before use, however, careful attention must be paid to operational safety and inspection
procedures. Therefore, before operating this electric hoist, please read the following instructions
and follow correct operational methods. Otherwise, it will not perform properly as is expected.
（A）
Before the installation, please ensure the delivery to have the exact specifications as you had
purchased. This machine has been subjected to strict inspection before delivery ex-work. In
case of any trouble caused during the handling process, please contact your local distributor or
service station. We shall provide best services to meet your satisfaction.
（B）Items to be inspected before operation :
1. Mount the hoist in position. Make sure to secure the power cords and control cables, so
as to avoid poor electrical connection.
2. For the wiring system, this machine must be grounded（green wire）to avoid slight
leakage caused by static charge.
3. Depress the button switch when the machine runs in idle and check if the UP （↑）and
DOWN （↓）operation is consistent with the switch indication.
4. The surface of chain（Wire ROPE）must be kept clean and oiled, to avoid the chain（Wire
ROPE）from interwinding.
5. To store the chain, lower the chain to the lower limit, mount the chain bag onto the hoist,
then, put the chain into the chain container.
6. Check the correct operation of the brake stop device.

（C）CAUTIONS FOR THE USE OF ELECTRICAL HOIST
1. For the sake of safety, do not apply a load in excess of the rated load.
2. Ensure if the load is tightly fastened?
3. Before applying the load, the chain（Wire ROPE）must be straightened to buffer the
impact.
4. The center of gravity of the load should be hoisted. Never operate unbalanced hoisting.
For inclined hoisting by the electric hoist, the inclination should be kept within 15°.（If
possible, try to avoid inclined hoisting.）
5. During the hoisting of load, allow no person to stay below or nearby the load, to avoid any
injury.
6. To move the electric hoist with a load, do not pull the control cable in a transverse
direction, so as to avoid the electric cable from being broken.
7. Make sure to depress the switch to the full limit. NEVER operate abrupt positive then
reverse rotation or inch movement.
8. During hoisting, try to keep the hook from reaching the upper and lower limits, so to
minimize the wear of the Clutch lining.
9. Astop device must be fitted when the transverse pulley reaches the terminal of l-beam, so
to avoid the hoist from damage or slipping off the end.
10. For outdoor use of electric hoist, keep the hoist from direct sunshine, rain and wind. There
should be a proper shelter (such as rain resistant hood, etc.)
11. There is a stop button on the lower hook to prevent the steel cable from escaping.
Therefore, make sure the cable is in the correct position on the lower hook and keep the
safety angle within 60°. (See diagram)
（D）Routine and regular inspection items of electrical hoist :
To ensure the proper performance of this machine and extend its service life, please make the
following routine checks.
D-1 Routine inspection items:
1. Depress the button switch and let the hoist run idle, check if the upward and downward
operation are normal?

2. Is the hoist operation smooth? Is there abnormal noise when it is with load?
3. Check if the chain is oiled or damaged?
4. Is the brake operation normal when the winding is stopped?
5. Is the lower hook wasily rotating?
D-2 Regular inspection items:
1. Inspection of LINK chain
LINK chain is the most important part of the electrical chain hoist, which is made of special
alloy steel with heat treatment. The purpose is to withstand wear and tension. In case the
surface is dried and rusted, it will cause interwoven chains which may break. Therefore,
the surface must be oiled frequently (use normal lubricating oil). In case the chain is
deformed, cracked, elongated, worn, in excess of the following standards, new parts must
be replaced:
CHAIN WEAR LIMITS: 10Φ
MEASUREMENT/DIAMETER 6.3Φ
7.1Φ
Original measurement 6.3Φ 7.1Φ 10Φ
Critical measurement d mm 5.7Φ 6.4Φ 9Φ
Original measurement 19.1 20.2 30Φ
Critical measurement p mm 20 21 3.1Φ
2. Inspection of gear:
a. Regular replacement of lubricating oil in the gearbox.
b. Check if the gear surface is cracked or worn.
3. Inspection of hook:
a. In case of abnormal deformation, damage or breakage at the opening of the hook, it
must be replaced with new.
b. In case the wear extent of the hook is in excess of 10%, it must be replaced with a
new part.
4. Inspection of pushbutton switch:
a. Are the inner and outer screws of the pushbutton switch loosened? Is the electric
wire damaged?
b. Is there foreign substance between the contact points?Are the contact points
abnormally worn?
5. Inspection of main unit:
a. Is the wiring system in the main unit secured? Is the electric wire aged or damaged?
b. Are the inner or outer screws of the main unit loosened?
c. Is the panel or casing of the main unit deformed?
