LUBRICATION
This tool has been lubricated with a sufficient amount of high grade lubricant for
the life of the unit under normal operating conditions. No further lubrication is
necessary.
FRAME PROTECTOR
The frame protector bar is made of hardened steel. It is located to the left and
the rear of the idler pulley and is fastened to the frame. This bar protects the
frame of the tool when tracking the abrasive belt. Adjust the belt so that it moves
evenly across (without rubbing) the protective bar. When this bar becomes worn
and uneven, replace it with a new one (available from your Porter-Cable Service
Center).
DRIVE PULLEY
The rubber-covered drive pulley at the rear of the tool is crowned or tapered
from the center to either side to make the abrasive belt run true and in line with
the idler pulley at the front of the tool. After considerable use, the crown will wear
away and the belt will begin to run off the side of the pulley and cut into the
guide block or frame. When the crown is worn to this extent, have the drive
pulley replaced by your Authorized Porter-Cable Service Station. This action can
be checked each time the abrasive belt is replaced and tracked. After the belt is
tracked to the front pulley, watch it for a few seconds to see that it runs true and
stays in place on the back pulley. Avoid getting oil and grease on the rubber
cover. It will cause it to fail.
BRUSH INSPECTION
For your continued safety and electrical protection, brush inspection and
replacement on this tool should ONLY be performed by an AUTHORIZED
