5 - Lubricate the Lifting Chains
Tools will be required to perform this procedure.
New parts will be required to perform this procedure.
Dealer service will be required to perform this procedure.
Use a spray lubricant designed for chain lubrication for best results.
Lubricated chains are essential to good machine performance and safe operation. Extremely dirty
conditions may require that the chains be cleaned and lubricated more often.
The direct result of wearing the transmission chain is to stretch the total length of the chain. Measure
the stretching rate of the used transmission chain by eye every three months. The mast connected
to the elongated chain would be lower in position so that the top of each mast is obviously uneven in
‘stored’ position. It may lead to damage on guide roller if the problem is serious.
Every link of the transmission chain is associated with three links of the
masts�����
Lower the platform to the stowed position.
Measure the maximum height of the

Result:
The machine should be lower
than specification.
