With platform in the stowed position;

• 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 10cm (4 in.), until the inner set of chains are visible through the chain
inspection hole.

NSPECTION
Refer to Figure 3-16: “Elevating Assembly,” on pageSection 3-20.
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.
From the lower controls, raise the platform and block the elevating assembly (see Figure 3-1: “Supporting
Elevating Assembly,” on pageSection 3-3).
• 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.
