SET UP
2. Feed the power wires through the strain relief on
the bottom of the control panel, tighten the strain
relief, connect the cord to the terminals shown in
Figure 18 or 19, and reinstall the control panel face
plate.
Note (Model W1773 Only): When using a phase con-
verter, connect the manufactured power leg to the
L1 terminal
(Figure 19). The L1 terminal can handle
power fluctuation because it is wired directly to the
motor. The other wires connect to the controls and
must be consistent to prevent damage
.
3. SHUT OFF THE MAIN POWER AT THE POWER SOURCE
CIRCUIT BREAKER
and attach the wires to the locking
shutoff switch.
Gear Oil Check
It is important to make sure the gear box has adequate oil
in it before running the sander for the first time, to ensure
the gears do not burn up.
To check the gear oil, do these steps:
1. Remove the shipping seal from the side of the vent-
ed fill plug (
Figure 20), if not already done so.
2. Check the sight glass shown on the back of the gear
box to make sure gear oil is present.
3. If the gearbox oil level is low, follow the steps on
Page 30 to refill the oil.
