To Avoid Health Problems
Never use used motor oils as a chain lubricant. Only
use chain oil as a lubricant on the load chain. The Chain
Block normally requires no additional lubricant except
for periodically lubricating the load chain as indicated or
when the unit is disassembled for periodic inspections,
cleaning or repairs. The brake is designed to operate dry.
Do not use any grease or lubricant on the braking surfaces.
When lubricating parts adjacent to the brake, do not use an
excessive amount of lubricant which could seep onto the
brake surface.
Using any grease or lubricant on the braking surfaces will
cause brake slippage and loss of load control which may
result in injury and/or property damage.
To Avoid Injury
Do not use any grease or lubricant on the braking surfaces.
The brake is designed to operate dry.
When the Chain Block is disassembled for periodic
inspections, check the pawl for free movement and apply
a light coat of WD-40 or similar lubricant to the pawl stud.
When the Chain Block is disassembled for cleaning or
repairs, the following locations should be lubricated using
approximately 29.5ml per Chain Block of suitable grease or
equivalent:
• gears
• liftwheel rollers
• gear bearing rollers
• chain guide and dead end pin
Note: To assure extra long life and top performance, be
sure to lubricate the various parts of the Chain Block using
the lubricant specified above.
Exterior Finish
The exterior surfaces of the Chain Blocks have a durable,
scratch resistant finish. Normally, the exterior surfaces can
be cleaned by wiping with a cloth.
Preventative Maintenance
In addition to the periodic inspection procedure, a
preventative maintenance program should be established
to prolong the useful life of the Chain Block and maintain its
dependability and continued safe use. The program should
include the periodic inspections with particular attention
being paid to the lubrication of various components using
the recommended lubricants.
Testing
Before using, all altered, repaired or used Chain Blocks
that have not been operated for the previous 12 months,
should be tested by the user for proper operation. First test
the unit without a load and then with a light load of 20kg to
be sure that the Chain Block operates properly and that the
brake holds the load when the hand chain is released. Next
test with a load of 100% rated capacity. In addition, Chain
Blocks in which load sustaining parts have been replaced
should be tested with 100% of rated capacity by or under
the direction of an appointed person and a written report
prepared for record purposes.
To Avoid Injury
Use only GT Viper supplied replacement parts. Parts may
look alike, however GT Viper parts are made of specific
materials or processed to achieve specific properties. Any
repairs to this chain block must be undertaken by a suitably
qualified and competent person. Following any repairs,
this Chain Block must be tested in line with the guidelines
set out in the current BS EN 13157 standard prior to its
reintroduction to service.
