ASSEMBLY
Drill Chuck and Arbor
The drill chuck is attached to the drill spindle by means of a drill chuck arbor. Matched tapers on the arbor and the back of the chuck create an almost permanent assembly when properly joined. To assemble the drill chuck and mount it to the spindle, carefully follow the instructions below:
Many of the solvents commonly used to clean machinery can be highly flammable, and toxic when inhaled or ingested. Always work in
1.The drill chuck, arbor and spindle socket must be thoroughly cleaned before assem- bly. It is recommended that mineral spirits be used for this task. Refer to the safety warnings on the container of the mineral spirits. Failure to clean the mating surfaces may result in separation and wear.
2.Use the chuck key provided to adjust the jaws of the chuck until they are well inside the drill chuck body.
3.Place the drill chuck on a workbench face down. The arbor has a short taper and a long taper. Place the short taper into the socket in the back of the drill chuck and tap
with a rubber or wooden mallet. See Figure
19.If the chuck fails to remain secure on the arbor, repeat step 1 and 2. Do not use excessive force. The drill chuck and arbor may be damaged.
DO NOT use a steel hammer on the drill chuck to seat it onto the spindle. Damage will occur to the chuck and/or spindle which may make them unusable or unsafe.

Do not use gasoline or other petroleum- based solvents to remove this protective coating. These products generally have low flash points which makes them extremely flammable. A risk of explosion and burning exists if these products are used. Serious personal injury may occur.
