PIT INSTALLATION -- MODELS WITH BEVEL TOE GUARDS
DANGER!
Do not install the lift in a pit unless it has a bevel toe guard or other
approved toe protection. A shear point can exist which can cause severe
injury to the foot.
1. Check the pit dimensions. Length and width should be 2" minimum longer and
wider than the lift platform. Depth should include ½” allowance for shims or grout.
2. Check the chase entrance into the pit. The diameter should be 3". If the
permanent electrical work is not complete, some means of temporary lines with an
on-off device for the motor should be set up for testing purposes.
3. Lower the lift into the pit and check for proper height. The lift should be solid and
flush with the pit angle framing. If needed, shim to the desired height. DO NOT
“spot” shim. Shim the full length of the base frame. This will prevent the frame
from sagging under an exceptionally heavy load.
CAUTION!
INSTALLATION INSTRUCTIONS
When moving the lift, do not attempt to pick it up by the platform; it is
hinged and could be damaged. Pick up the lift from under the base frame
ONLY using lifting eyes or a strap sling.
4. Check wiring connections to the motor for proper rotation of the actuator.
5. Make temporary electrical connections. Raise and lower the lift to make positioning
adjustments and align the platform in the pit with a proper clearance of 3/4” minimum
around the edges from the platform to the pit angle.
