ROUTINE INSPECTION

It is recommended that you periodically inspect your
spindle sander as a precautionary action. During this
time, check for the following:
• Inspect all hardware, fittings and fasteners that may
have loosened due to vibration and re-tighten as
needed.
• Check for dust and/or wood particles that may have
accumulated on or in the machine. Check all dust
collection fittings – re-tighten as needed.
• Inspect the ON/OFF SWITCH for damage before each
use. Periodically inspect the power cord and plug for
damage. If necessary replace the power cord and the
plug at the first signs of visible damage.
• Check all table inserts, spindles and sanding sleeves
for damage and replace if necessary.

BEARINGS

This floor spindle sander features factory-sealed
bearings. A sealed bearing requires no lubrication
during its lifetime. Should a bearing fail, your spindle
sander will probably develop a noticeable rumble,
which will increase when the machine is put under load.
Bearings must be replaced when this occurs.
A complete line of accessories is available from your DELTA

our Web Site www.DeltaMachinery.com for an online catalog or for the name or your nearest
supplier.
Since accessories other than those offered by DELTA
accessories could be hazardous. For safest operation, only DELTA

TO CHANGE THE GEAR OIL:
See Figure 13
Gear oil should be changed at 800 hours of use
with a high-quality 90 Wt. SAE gear oil. The oil level
sight glass (B) is located at the back of the gear
box (A), on the left side near the motor. The sander
takes approximately 2 quarts. The oil level should be
checked at least monthly and oil added when indicated
in the oil level sight glass. The oil fill cap is on top of
the gear box and is visible as you look down on the
spindle.
1. Open the access door located on the rear panel of
the cabinet.
2. The oil drain valve and drainage tube (C) are
located on the left side of the gear box. Place a
catch basin beneath the clear drain line and open
the valve to drain the gear oil.
3. Close the valve, remove the catch basin, and close
the access door on the cabinet.
IMPORTANT: Check your local and/or state
environmental codes to ensure that you properly
dispose of all used oil.
4. Locate the oil fill cap. It is located on top of the
gear box and is visible as you look down on the
spindle. To provide easier access to the fill cap,
remove the spindle.
5. Refill the gear box using a high quality 90-weight
SAE gear lube oil.
6. Replace fill cap.
