WEEKLY MAINTENANCE — LUBRICATION
When any work is to be done on body or hoist and body is fully or
partly raised, body must have both props securely set or be blocked
securely so it cannot fall. In addition, the HOIST control lever must
be in neutral with the hoist lever lockout engaged in the "lock" posi-
tion and the PTO disengaged.
1. The hoist should be lubricated at least once a week. See gure
12. Use the same grease as recommended for the chassis. Use
oil on control rod ends, cable, cable levers and link ends.
2. Check hydraulic oil level for proper level as follows:
Double-Acting Hoist — Extend cylinder to full stroke, block
body securely and check oil level in tank by removing oil level
plug. Oil should be level with plug opening. Add oil if neces-
sary.
Single-Acting Hoist — Extend cylinder to full stroke, block
body securely and check oil level in cylinder by removing vent
tting from top of cylinder. Oil should be level with vent tting
opening. Add oil if necessary.
