WARNING:
MAINTENANCE
NOTE:
WARNING:
All components should be cleaned and coated with a light film of oil prior to use.
Use a clean, non-detergent oil, preferably SAE 10 (90 SSU) or lighter.
The air supply for the Model 302A with an air motor should include an adequate filter,
regulator and lubricator (FRL).
The Motor Warranty is void if damage occurs from contaminated air or lack of
lubrication.
If the Model 302 is operated in the vertical position (cutting head up), turn it upside
down and remove the chips and/other debris after each bevel has been completed.
Tool life may be severely shortened, unless chips and/or debris, that have
been deposited on the cutting head during the machining operation, are re-
moved.
Bearing and gears are to be lubricated using a high string utility grease (P/N 68-
0020).
AIR MOTOR LUBRICATION
Disassembly of a power unit voids warranty, except when performed by a
TRI TOOL designated repair technician. (Letter of designation is required.)
No direct maintenance is normally required on the Air Motor.
However, the air supply must flow through a filter/regulator/lubricator (FRL) unit or
separate units before arriving at the air motor.
The FRL unit must be maintained as required (frequency dependent on the basic air
supply) to keep the water trap drained, filter cleaned and the lubricator oil reservoir
filled so that a drop of oil every two (2) to five (5) seconds is flowing.
If the Model 302A is to be left idle for 24 hours or more after being run on ‘wet’ air, it
is advisable to squirt oil directly into the air motor inlet and run the motor for two (2)
to three (3) seconds.
This will prevent rusting and ‘freezing’ of the rotor vanes.
