MAINTENANCE (CONT.)
HYDRAULIC SYSTEM
Your hydraulic system is maintenance free. Do not add hydraulic oil unless there is, or was, a leak.
Use Premium HVI hydraulic oil or equal. Other oils, fluids, or solvents may damage your hydraulic
system. If you suspect additional oil is required, follow these steps:
1. Check for and fix any possible oil leaks.
2. Lower the truck and load with 600 lbs. (approximate).
3. Pump the truck to its maximum lift height.
4. Measure the vertical height of the exposed piston (215030) and refer to the chart below.
ADDING OIL (IF REQUIRED)
1. Place and secure the truck on its right side (release valve facing the floor).
2. Pull up on the release lever (PL-40274BDM) and extend the lift piston fully.
3. Remove screw (221586) and add the amount of oil determined by the chart in step 4.
4. Reinstall screw (221586) but do not tighten. Leave a 1/32 in. gap.
5. Pull up on the release lever (PL-40274BDM) and collapse the lift piston until oil starts to
ooze from the screw.
CAUTION! - It is extremely important that step 5 is performed. Otherwise, air in
the pump can force out the wiper seal (20066). Take care when adding oil not to
introduce impurities into the hydraulic system.
6. Tighten the screw (221586) fully and return the truck upright.
