Hydraulic Oil Replacement
1. Drive the forklift to the maintenance ditch, switch off the truck, remove the key and press
down the Emergency Disconnect Switch.
2. Fully lower the forks, apply the hand brake, and place a container below the oil drain of
the tank. Unplug the oil drains plug at the bottom of the oil tank and drain the hydraulic
oil.
3. Before putting the plug back on, make sure that the seal ring is complete and intact and
then secure the plug (Torque: 33.19 ft-lbs).
4. Add a small amount of hydraulic oil first to check if the seal ring on the drains plug is ok.
Tighten the plug if oil leakage occurs.
5. Add hydraulic oil into the oil tank and measure the oil level with the dipstick.
6. Remove and clean the residual oil spill on the oil tank and forklift bottom and working
area.
CAUTION
1. Comply with local regulation on measures of precaution for handling oil. When disposing
the waste oil, keep children away and do not pour it into the sewer or onto the ground.
2. Do not mix different types of hydraulic oil.
3. Using unauthorized hydraulic oil might cause damage to hydraulic system.
4. Use only authorized hydraulic oil. If you need to switch to other types of hydraulic oils,
contact with the BYD forklift after sales service people.
Note
1. If the average oil temperature stays between 104 ~ 140 °F, it is recommended to use ISO
VG46.
2. If the average oil temperature exceeds 140 °F, it is recommended to use ISO VG68.
