Forward-Reverse Switch (3-Phase)
The three phase model of the DS20 has a
Forward-Reverse switch (Figure 12). When
changing direction with the Forward-Reverse
switch, turn the lever to the OFF position and
allow the disc to come to a complete stop. (Use
the brake for immediate stop). Then turn the
lever to the opposite direction, and allow the
disc to come up to speed.
Brake
Pull the brake handle until the pad contacts the
rotating disc.
Apply the brake only when
the switch is OFF (On the three-phase model,
only when the main switch is OFF, or the
Forward/Reverse switch is OFF). Damage to
the machine can occur if the brake is applied
while the switch is ON.
Maintenance
Before doing any
maintenance on the machine, disconnect it
from the electrical supply by pulling out the
plug or switching off the main switch!
Failure to comply may cause serious injury.
The DS20 Sander requires minimal
maintenance. Periodically, make sure the rack
and the trunnions on both sides of the table
(Figure 13) are lubricated with a good grade,
non-hardening grease.
The table surface must be kept clean and free of
rust for best results. If rust appears, use a
mixture of household ammonia, a good
commercial detergent and #000 steel wool.
Alternatively, commercial rust removers can be
found at many hardware stores.
Apply a light, protective coating over the table,
such as paste wax. Products in aerosol form are
also available in hardware stores and supply
catalogs. Whatever method is chosen, the
coating should protect the metal and provide a
smooth surface, without staining the wood.
If the power cord is worn, cut or damaged in any
way, have it replaced immediately.
