Page 12: Maintenance
• 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. - Page 13 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: 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.

Page 15: Cylinder Replacement
When replacing a gas cylinder, make sure not to scratch, mar, or nick the shaft on either the old cylinder being replaced, or the new cylinder being installed. All warranty cylinders must be returned to FlexArm for evaluation. The warranty is void if the cylinder to be evaluated shows signs of scratches or nicks on the cylinder shaft or body. - Page 16 6. Remove the upper arm screw as shown in Figure 10. Only remove 1 screw (does not matter which side). Using an Allen wrench or pin punch, push the arm pin completely out, leaving the wrench or punch in place. CAUTION: Make sure not to damage the arm pin threads.
- Page 17 11. Raise the bottom two arms in the horizontal position and place onto a riser. The riser should be approximately 14” tall and be capable of withstanding 150 lbs. of force. The angle mount should be positioned in a straight line with the arms. See Figure 12.
