UBRICATION
Refer to Figure 3-16: “Elevating Assembly,” on page Section 3-20.
With platform in the stowed position;
remove the platform mast cover (43).
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 (44).
raise platform approximately 10cm (4 in.), until the inner set of chains are visible through the chain
inspection hole.
apply enough aerosol chain lubricant to the exposed chain to allow the lubricant to run down the chain.
replace chain inspection cover.

NSPECTION
Refer to Figure 3-16: “Elevating Assembly,” on page Section 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 (43) to look for worn pulleys (11 & 13) or damaged
components.
Inspect the chain anchors (7,10 and 12) 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 page Section 3-3).
Inspect the inner chain anchors (9, 30 and 31) 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.

DJUSTMENT
1. Elevate the platform and support the elevating assembly, see section 3.1.
2. Adjust the tension in the ropes to ensure they will stay seated in their pulley wheels during lift and
lowering as shown in the below picture, you should just be able to pull each rope against
the outer
mast with one finger.
3. Raise the platform to its full height and visually inspect each rope for damage.
