Slide Block Adjustment
Annually check for wear on the slide blocks and replace or retighten as necessary. If the
lift exhibits excessive mast sway, it is probable that the slide blocks need adjustment. The
slide blocks should be adjusted so that there is no air gap between the slide block and the
mast the slide block is moving against. There are 12 slide blocks, 6 upper and 6 lower.
The adjustment procedure is the same for all slide blocks. Three upper slide blocks are
shown in Figure 3-6.
1. Loosen, do not remove, the slotted hex head screw securing the slide block to be
adjusted.
2. Using an allen wrench, turn the set screws in (clockwise). This will push the
block in against the next mast. Do not overtighten. Tighten the slotted hex head
screw to secure the slide block in position.
3. Check all slide blocks and make adjustments as necessary.
4. After all adjustments are made, fully extend the lift. If the platform can be low-
ered without stopping then the blocks are properly adjusted.

NOTE: The plastic slide blocks in the mast are made of a bearing material which
has a high degree of lubricity and need only be kept clean. However,
precautions should be taken to ensure that the paths along which the
blocks move are kept clean and lightly lubricated with a dry type silicon
lubricant.
