Jet Tools 22-44 Pro Adjustments, Extension Cords, Switch Lockout, Dust Cover

Extension Cords

If an extension cord is necessary, make sure the cord rating is suitable for the amperage listed on the machine's motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.

The chart in Figure 20 shows the correct size cord to use based on cord length and motor plate amp rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Adjustments

Switch Lockout

Unauthorized use of the sander can be prevented by pulling out the key (Figure 21). Press switch to OFF position before removing the key. When the key is removed, the drum can not be started. (Note, however, that the conveyor belt can still run when the key is removed).

To replace the key, slide it back into the switch until it snaps.

Dust Cover

To access the drum, lift the front of the dust cover using the handle and push back the front cover all the way to secure it in open position. The dust port should be on the back or outfeed side of the sander.

When removing the dust cover for initial drum alignment or other reasons, lift the front cover half-way and pull the dust cover out from the outfeed side of sander. The edges will pop out when the dust cover is pulled from the carriage leg brackets. Reverse this procedure to re-install the dust cover.

The dust cover should not require removal for fine tuning alignments or for changing or cleaning the abrasives.

Table Height Control

NOTE: Read “Table Support Screws”, page 9, before operating the handwheel.

The table height and depth of cut are controlled by the height adjustment handwheel (see Figure 6). Rotating the handwheel raises or lowers both sides of the table simultaneously by transferring the handwheel rotation through the miter gear and transfer rod assembly.

Check the operation of the height adjustment mechanism. If it does not operate smoothly or easily, check the following:

Recommended Gauges (AWG) of Extension Cords

*based on limiting the line voltage drop to 5V at 150% of the rated amperes.

NR: Not Recommended.
