7.1. Daily Maintenance Check
7.1.1. Check the state of the wheels and the axles since thread, rags and other foreign objects can jam the wheels making safe, effective
operation difficult.
7.1.2. On completion of each task, unload the forks and return them to the lowest position.
7.2.
Oil Check
7.2.1. Check the oil level at six monthly intervals. Sealey hydraulic jack oil is used with the pallet truck. The viscosity of the oil should be
30cSt at 40°C. The amount used in the pallet truck is approximately 0.4 litres.
7.3 Lubrication
7.3.1. The bearings and shafts of the pallet truck have long-life grease applied to them during manufacture. The bearings will only require
.greasing at monthly intervals or after the pallet truck had been serviced down to the lubrication points.
7.4. Purging Air from the Hydraulics
7.4.1. Air can get into the hydraulic oil through transportation, or the pump becoming misaligned. As a result, the forks will not elevate.
7.4.2. The air can be purged by setting the control level to the LOWER position and pumping the operating handle up and down for 30 - 40
seconds.
7.4.3. When the pallet truck is not in use, lower the forks and park the truck where it will not be a hazard.
