MAINTENANCE
5.01 Maintenance Schedule
The QRC TM -2000 will require a periodic maintenance
schedule to ensure an optimum service life. The following
maintenance checks are required. Depending on the use
of the unit, each specific application could require a more
extensive schedule.
Daily
Ensure incline housing area is clear of excessive
spatter.
Visually check oil level in lubricator reservoir.
Weekly
Ensure incline housing area is clear of excessive
spatter.
Visually check lubricating oil level in lubricator
reservoir. The life of the air motor is dependent on
a sufficient supply of lubricating oil. Replenish this
oil as needed.
Inspect air lines and connections for leaks.
Check interface cables for frayed connections or
bad wiring.
Quarterly
The QRC TM -2000 reamer blade life will depend on the
application.
At least quarterly the reamer blade should be inspected
for dullness, clogging and breakage.
Visually check lubricating oil level in lubricator reservoir.
Ensure incline housing area is clear of excessive spatter.
Yearly
The clamp block should be cleaned and inspected
for excessive wear and replaced if needed.
Visually check lubricating oil level in lubricator
reservoir. Replenish this oil as needed.
Inspect air lines and connections for leaks.
Check interface cables for frayed connections or
bad wiring.
Remove top plate and apply grease on cam slides
on top (V-Block) and side plates.
