INSTALLATION
Prior to installing hoist, carefully inspect it for possible shipping damage. Hoists are supplied fully lubricated from the factory. Lubrication of the load chain is recommended before initial hoist operation.
•Depending on model selected, hoist may weigh up to 485 lbs. (220 kg). If parts of the hoist are dropped, they can cause injury, death or property damage. Adequately support hoist during installation.
•Owners and users are advised to examine specific, local or other regulations, including ASME standards and/or OSHA Regulations which may apply to a particular type of use of this product before installing or putting hoist to use.
The VL2 manual chain hoist must be used in a vertical position to provide a straight line pull from top to bottom hook. The hoist must be positioned so that it does not contact the support members when in use. When operating in limited areas suitable lifting attachments or slings must be used to prevent hoist body and hand chain from being obstructed.
Initial Operating Checks
Operate hoist with a test load (10% of rated capacity) by raising and lowering this load several times. Verify brake operation with this light load prior to applying heavier loads.
•Each time a load is lifted, the operation of the brake should be checked by raising load slightly and stopping to ensure brake will hold load before continuing to lift.
Familiarize operators and personnel responsible for hoist installation and service with ASME B30.16 specifications and this manual prior to placing unit into service. All requirements of this specification, including testing should be met before approving hoist for operation.

Installing Chain Container
Refer to Dwg. MHP0321 on page 19. Position chain container to ensure minimum contact with handchain. On larger
OPERATION
The four most important aspects of hoist operation are:
1.Follow all safety instructions when operating hoist.
2.Allow only personnel trained in safety and operation of this hoist to operate hoist.
3.Subject each hoist to a regular inspection and maintenance procedure.
4.Be aware of the hoist capacity and weight of load at all times.
•Hoist is not designed or suitable for lifting, lowering or moving persons. Never lift loads over people.
Hoist Operation
When facing hand chain side of hoist:
Pull down on right hand chain (clockwise) to raise load.
Pull down on left hand chain (counterclockwise) to lower load.
On 15 and 20 ton hoists, use two operators, one on each of the two hand chains. To keep the load chain centered in the block assemblies, operate hoist units simultaneously and at the same speed. An equal amount of unloaded chain must be maintained under each hoist body.
•Do not allow load chain, on 15 and 20 ton hoists, to accumulate on one side (under one hoist body). Excessive loading to load chain anchor may occur resulting in a falling load which can cause death, injury or property damage.
