OIL
Please check the oil level every six months. The oil
capacity is about 0.3L. Restore the fluid level in the
reservoir to 5mm below the top; this must be
done with the forks in the DOWN position.
Use hydraulic oil ISO-VG32 or equivalent.
Oil viscosity should be 30cSt at 104°F (40°C).
HOW TO EXPEL AIR FROM THE PUMP UNIT
Air may enter the unit over time or when the seals are
replaced. To expel the air, lift the control lever to the
DOWN position and move the handle up and down
several times.
DAILY CHECK AND MAINTENANCE
Daily checks of the pallet truck can limit wear and tear
on the unit. Pay special attention to the wheels, the
axles, the handle, the forks and lift and lower control.

Use motor oil or grease to lubricate all movable parts.
