WARNING !
Before maintaining lift, read & follow the recommended safety
practices in the Safety Practices section. Failure to follow these
safety practices could result in death or serious injury.
DANGER !
Do not work under lift without Maintenance Device! To avoid
personal injury, NEVER go under the lift platform until the load
is removed and the scissors mechanism is securely blocked in
the open position and the appropriate OSHA lock-out/tag-out
procedure is followed . See "Lift Blocking Instructions" section
DANGER !
Failure to relieve lift table system pressure could result in the
sudden and unexpected release of pressure during maintenance
and/or repair of the lift and result in severe injury to personnel
and/or damage to the lift.
1. NEVER TRY TO DISASSEMBLE OR REPAIR A PUMP IN THE FIELD. These
pumps are high-precision devices requiring extreme precision in fit-up. When
one is damaged, there is seldom anything that can be repaired in the field. It is
also more economical to replace a pump than to refit old parts with new parts.
2.
The roller pin or roller bushing should be replaced whenever excessive wear is
detected. The rollers are furnished with a pressed-in lifetime-lubricated bushing.
PIPE THREAD SEALANT
Loctite PST #567 pipe thread sealant or equivalent is recommended. Do not use
Teflon tape. Tape fragments can cause malfunctioning of the hydraulic system.
