3. TO ADJUST RELEASE DEVICE
On the handle of the pallet truck, you will find the control lever (81) which can
be set in three positions (See Fig. 4): LOWER=to lower the forks; NEUTRAL=to
move the load; ASCENT=to raise the forks. After assembling the handle, you
can adjust the three positions.
3.1 First tighten the setting screw (59) on the cam (56) until the LOWER
position function works.
3.2 If the forks elevate while pumping in the NEUTRAL position, turn the
setting screw (59) clockwise until pumping the handle does not raise the
forks and the NEUTRAL position functions correctly.
3.3 If the forks descend while pumping in the NEUTRAL position, turn the
setting screw (59) counter-clockwise until the forks do not lower.
3.4 If the forks do not descend when the control lever (81) is in the LOWER
position, turn the setting screw (59) clockwise until raising the control
lever (81) lowers the forks. Then check the NEUTRAL position as per item
3.2 and 3.3.
3.5 If the forks do not lift while pumping in the ASCENT position, turn the
setting screw (59) counter-clockwise until the forks elevate while pumping
in the ASCENT position. Then check the NEUTRAL and LOWER position as
per item 3.2, 3.3 and 3.4.
4. MAINTENANCE
4.3. Oil
Please check the oil level every six months. The volume of oil is about 0.3lt. Use
the hydraulic type oil according to temperature scale below.
Temperature Oil
-20°C~+40°C L-HV32 Hydraulic oil
4.4.How to expel air from the pump unit
Air may get into the hydraulics during transportation or when a pump is stored
upside down. This can prevent the forks from lifting while pumping with the
lever in the ASCENT position. The air can be expelled in the following way: Lift
the control lever to the LOWER position, then move the handle up and down
several times.
