Notes: 1. Be certain to lubricate like items on each side of the machine.
2. Recommended lubricating intervals are based on normal use. If machine is subjected to severe operating conditions, such as a high
number of cycles, location, corrosive/dirty environment, etc, user must adjust lubricating requirements accordingly.
3. Lubricating intervals are calculated on 50 hours of machine operation a week.
4. Prior to checking hydraulic oil level, operate machine through one complete cycle of lift function (full up and down). Failure to do so will
result in incorrect oil level reading on the hydraulic reservoir.
