MAINTENANCE:
•
Oiling the Motor:
If the FlexArm has been sitting a while between jobs, it may be necessary to add 4-5 drips of oil directly
into the motor inlet to place oil on the vanes before running. It will take the lubricator a short time to
actually get the oil to the motor when first running the unit. The lubricator must be checked periodically to
ensure that the flow rate of 1-3 drops per minute is maintained.
•
Cleaning the FlexArm:
The FlexArm should be periodically cleaned and free of dirt, debris, grinding dust, etc. An airline can be
used to blow the dust and chips away from the arms, arm joints, motor, chuck, etc.
Never use oil, WD-40,
or any other lubricant to lubricate the arm joints (arm joints are constructed with self-lubricating bushings
and require no maintenance). Never use harsh cleaners or solvents. Never allow any cleaning agent to
reach the arm joints.
•
Periodically check the bolts throughout the unit for tightness:
If the bolts have loosened up, use Loctite 242 (blue) on the threads and reassemble. This should prevent
any further problems.
•
Filter / Lubricator:
Check that the filter/lubricator is set for approximately 1-3 drops per minute as indicated in the
INSTALLATION of this manual. Always use 10 wt. hydraulic oil or light spindle oil. (EP-32 hydraulic oil is
recommended). Never use Marvel Mystery Oil or synthetic products. Make sure to clean the filter and
drain excess water from the filter bowl on a regular basis.
•
Motors with a quick-change chuck:
Keep both the motor and the chuck free from contamination by cleaning regularly: An airline can be used
to blow dust, dirt, and debris off of the motor and chuck collar. Make sure to clean inner surface of the
chuck as well. If contaminants build up too excessively, it may become necessary to soak the entire chuck
in cleaning solvent or WD-40 type penetrating oil before using the airline. Doing this regularly will
considerably reduce, and may even eliminate, the need to disassemble the quick-change chuck to clean it.
If, however, the chuck has accumulated so much dirt and grime that disassembly is necessary, follow the
procedures given below:
o
Quick Change Chuck with Knurled Collar:
Lift the snap ring out of the groove and slide it towards the motor, resting on the chuck body. The
collar can then slide along the chuck body, exposing the compression spring and the two ball
bearings. (
CAUTION:
The ball bearings are held in place only by the collar; be careful not to lose
these ball bearings!) Clean the exposed area of the chuck body, the spring, and the two ball
