5.0 MAINTANCE
• Please check the oil every six months , we suggest you use hydraulic oil: ISO
VG32
• Whilst in transit air may enter into the hydraulic pump, this may result in the
forks not raising when first used. Please move the handle up and down
several times to allow air to escape.
• Routine maintenance is necessary. You should focus on the wheels and
handle assemblies. When the truck is not in use, remove the items on the
forks, and reset the forks to their lowest position.
• All the bearings and axles have been lubricated, please check at regular
intervals
