Drive Chain Tensioning

WARNING
!
Electricity can kill. Prior to performing any work on the AutoSet
Plus, verify that all power to the machine has been turned off
following OSHA-approved lockout/tagout procedures
(OSHA REGULATION 29 CFR 1910.147).
The drive chain is located under the drive chain cover.
When properly tensioned there will be no more than ½"
of slack in the chain.
Step 1. Remove the four bolts attaching the drive chain
cover to the gantry head cover.
Step 2. Remove the drive chain cover exposing the
drive chain (Figure 63).

4 Jam Nut (x4) – one on each corner of the motor mount plate.

Step 3. Using a 1-1/2 inch wrench loosen the nuts
located on each corner of the motor mounting
plate (Figure 63).
Step 4. Tighten the jam nuts 1/8 of a turn at a time
until the chain has ½ inch of slack.
Step 5. Make final adjustments to ensure the motor
mounting plate is level with the gantry cover.
This is best checked by measuring the distance
between the gantry cover and the motor
mounting plate at each corner. The height
should be the same at each corner.
Step 6. Tighten the nuts on each corner of the motor
mounting plate.

Guide Wheel Adjustment

Guide wheels are located at the bottom four corners of
the EasyRider Gantry (Figure 64). The guide wheels roll
against the table frame as the gantry head moves.
2
If the wheels are jamming up or skipping against the
frame they must be adjusted as follows:
Step 1. Position Gantry so the hood is close to a slot in
3
the table, visually compare hood to slot, they
should be parallel.
4
Verify that all power to the machine has been turned off
following OSHA-approved lockout/tagout procedures
(OSHA REGULATION 29 CFR 1910.147).
Step 2. Measure distance from the tube (where guide
wheel runs) to inside edge of Gantry "A" frame
at all four corners. The distance from the left
and right side of the same "A" frame should be
the same, and the distance between the "A"
frames from bottom chord side and top chord
side should be within ½ - ¾ inch of each other.
Step 3. To square the gantry to the table, use a wrench
to loosen the two bolts holding the housing to
the frame to create space between the wheels
and the frame of the table.
