daily check and mainTenance
Daily checks of the pallet truck can limit wear as much as possible. Special attention should
be paid to all moving parts; including wheels and axles, to ensure no foreign objects have been
picked up which may damage or hinder movement or safe operation.The forks should be unloaded
and lowered to the lowest position after each job is finished.
luBricaTion
All bearings and shafts are prepared with long-life grease at the factory. Lubrication with long-life
grease is needed at monthly intervals or after the truck is cleaned thoroughly at the lubrication points.
