Important: Manufacturer's warranty is void if tool is disassembled before warranty expires.

Please refer to parts breakdown for part identification.

13. Using 96243 Bearing Press Tool ( ordered separately ) press 02057 Bearing onto rotor and into 51923 Rear Bearing Plate hole until it is seated. Important: Cylinder must

fit snug between bearing plates. If too tight, rotor will not turn freely. Rotor must be lightly tapped at press fit end until rotor spins freely while still maintaining a snug fit. A

loose fit will not achieve the proper preload on motor. While pressing 02057 Bearing, make certain to contact inner race of bearing.

14. Add one drop of Loctite

243 (or equiv.) to governor assembly male thread and screw governor assembly into place (Left Hand Thread) with slotted screw head.

18. Rotate motor housing/gear casing and 53650 Lock Ring until throttle lever is located between the 6-9 o'clock position. Throttle lever in this position safe guards against

accidental start ups of the tool. Torque lock ring to 35 N•m (310 lb.-in.).

19. Place well lubricated 53608 Wick against 96325 Bearing with flat edge towards pinion gear. (Wick must be completely saturated with Dynabrade 95848 Gear Oil before

installation). Note: Do not contaminate wick with any other oil or grease product.

Tool Assembly Complete. Please allow 30 minutes for adhesives to cure before operating tool.

Important: Before operating, place 2-3 drops of Dynabrade Air Lube (P/N 95842) directly into inlet with throttle lever depressed. Operate tool for 30 seconds to allow air lube to

properly lubricate internal motor components. Motor should now be tested for proper operation at 90 PSIG max. If tool operates at a higher RPM than marked on the tool or if

vibration and sound levels seem abnormal, the tool should be serviced to correct the cause before use.
