If however they have been changed, you can adjust according to following step:
3.1 If the forks elevate while pumping in the DRIVE position, turn the adjusting nut (104)
on the adjusting bolt(103) or screw(318) clockwise until pumping action does not
raise the forks and the DRIVE position functions properly.
3.2 If the forks descend while pumping in the DRIVE position, turn the nut(104) or
screw(318) counter-clockwise until the forks do not lower.
3.3 If the forks do not descent when the control handle (117 or 120G) is in the LOWER
position, turn the nut(104) or screw (318) clockwise until raising the control
handle(117 or 120G) lowers the forks. Then check the DRIVE position according to
item 3.1 and 3.2 to be sure the nut (104) and screw(318) is in the proper position.
3.4 If the forks do not elevate while pumping in the RAISE position, turn the nut (104) or
screw (318) counter-clockwise until the forks elevate while pumping in the RAISE
position. Then check the LOWER and DRIVE position according to item 3.1, 3.2 and
item 3.3.
4. MAINTENANCE
The pallet truck is largely maintenance-free.
4.1 OIL
Please check the oil level every six months. The oil can be hydraulic oil: ISO VG32, its
viscosity should be 30cSt at 400C, total volume is about 0.4lt.
4.2 TO BANISH THE AIR
The air may come into the hydraulic oil because of transportation or pump in upset
position. It can cause that the forks do not elevate while pumping in the RAISE position.
The air can been removed in the following way: let the control handle (117 or 120G) on
the LOWER position, then move the draw-bar up and down for several times.
4.3 DAILY CHECK AND MAINTENANCE
Daily check of the pallet truck can limit wear as much as possible. Special attention
should be paid to the wheels, the axles, as thread, rags, etc. It may block the wheels.
The forks should be unloaded and lowered in the lowest position when the job is over.
