SCRUB BRUSH IDLER PLUGS
There are two grease fittings which are used to
lubricate the scrub brush idler plugs. The grease
fittings are located in the center of each idler plug
and are covered with plastic caps. Snap the caps
open to apply grease to the fittings. Use
Lubriplate EMB grease (TENNANT Part No.
01433--1). Wipe off all excess grease and replace
the plastic cap. Apply grease to the fittings after
every 50 hours of operation.

REAR WHEELS
The rear wheels have automotive-type bearings.
Repack the bearings with automotive type wheel
bearing grease after every 2000 hours of
operation.
SCRUB BRUSH DRIVE CHAINS
Each scrub brush is driven by a chain assembly.
Each chain case should be filled with SAE 30
engine oil to the oil level plug. Add oil through the
round cover at the top of the case. Check the oil
level after every 50 hours of operation.
POWER WHEEL
The power wheel is a gear reduction unit used to
drive the machine. Each front wheel is equipped
with its own power wheel that is driven by an
electric motor. The power wheels are lubricated
with SAE 90 mild to extreme pressure lubricant.
When the fill plug is in the three o’clock position,
add lubricant until it seeps out of the fill hole.
Check the lubricant level after every 200 hours of
operation.
