With platform in the stowed position;
• remove the platform mast cover (5).
• apply enough aerosol chain lubricant to the exposed portion of all four chains to allow the lubricant to
run down the chains.
• replace the cover.
• remove the chain inspection cover (8).
• raise platform approximately 10 cm (
4 in. ), until the inner set of chains are visible through the chain
inspection hole.

Refer to Figure 2-16: “Elevating Assembly,” on page 2-19.
At the same time as the chain lubrication task, inspect all elevating assembly components for wear.
With the platform in the stowed position;
• inspect the system through the platform mast cover (5) to look for worn pulleys (13 & 15) or damaged
components.
• Inspect the chain anchors (10a &10b) and visible portions of lift chain as you lubricate it.
• Look for cracks in the chain links, kinks in any portion of chain, and excessive corrosion.
Using the Lower Controls, elevate the platform and block the elevating assembly (see Figure 2-1: “Sup-
porting Elevating Assembly,” on page 2-3).
• Inspect the inner chain anchors (9) and the ends of the chains for damage or worn parts. If damage is
present, replace the components.
IMPORTANT: There are two pairs of two chains each, for a total of four chains. If only one chain of either pair is
damaged, both chains in the pair must be replaced.
