ADJUSTMENTS (Continued)
LIFT CHAIN AND PLATFORM ADJUSTMENT
The roller chain used to drive the platform vertically has
an adjustment to align the platform to the machine main
frame at the top position.
To adjust, raise the platform to the top position. Remove
the removable back panel. Adjust the 5/16-18 Hex Jam
Nuts and 5/16-18 Jam Nylon Lock Nut on the Rod ends
attached to the roller chain until the platform aligns to the
main frame. See FIG 4.
BRAKE TRAVEL ADJUSTMENT
The brake foot that contacts the floor can be adjusted
to assure the Platform Lift System holds position when
the brake is applied.
To adjust the brake foot contact to the floor, remove the
removable back panel and loosen the 1/2-13 Hex Jam
Nut and adjust the brake foot higher or lower by turning
the brake foot as required and then retighten the Jam
Nut. See FIG 5.
CAUTION: If the foot is adjusted with to much frame lift,
the Platform Lift will become unstable when the brake
is applied. The brake should be adjusted only enough
so the Platform Lift locks to the floor.
Reinstall the removable back panel before operating.
