Operating conditions
1. Compressor must be able to deliver 14.2 CFM,
70-100 PSI, and be rated at 3HP minimum for
models JSM-606/610/612. Models JSM-
620/630 require a compressor delivering 18-24
CFM rated at 5HP minimum.
2. Use 3/8” air hose between the compressor and
the sander.
3. To avoid moisture damage to the sander, use
an inline filter to trap moisture and an inline
oiler to keep the sander running at top
efficiency. These are placed inline between the
compressor and the sander. See Figure 1.
For further information, see “Air Tools – Instruction
and Care” enclosed with the sander.
Figure 1
Before operation
Disconnect sander from air
hose before making any repair or adjustment.
Failure to comply may cause serious injury.
1. Run compressor and blow out hose before
connecting sander to clear line of any
contaminants.
2. Before connecting the hose to the sander, add
4 to 5 drops of air tool oil to the air inlet.
3. If an inline oiler is not used, add 4 to 5 drops at
the air inlet for every three to four hours of
operation.
4. Adjust head to desired angle and tighten hex
socket cap screw (A, Figure 2), with hex
wrench supplied.
Always tighten hex socket
cap screw firmly after adjustment, or the
head could rotate causing loss of control.
