Note: Spring washers must be stacked exactly as
shown. A spacer may be included in the spring stack
and must be installed under the bottom washer
against the spring case. Align the bore of the spring
washers to clear the 7/8" O.D. of the spindle.
LUBRICATION:
An automatic in-line filter-lubricator is highly
recommended. This will supply the tool with clean,
lubricated air; keep it in sustained operation; and
increase tool life.
The in-line lubricator should be regularly checked and
filled with a good grade of 10W machine oil. In the
event an in-line lubricator is not used, the tool should
be disconnected from the air supply several times
daily and several drops of oil poured into the tool's air
inlet bushing.
The right angle drill head should receive a generous
amount of "Lubriplate #907" grease every fifteen (15)
to twenty-five (25) hours of "actual motor running"
time through the two (2) flush type grease fittings in
the right angle housing. "Lubriplate # 907" may be
purchased in a 5 gallon can using Part No. 107210.
GENERAL MAINTENANCE:
Tool Maintenance and Pressure Test Equipment
Kit 381273 is available and can be used for some
trouble shooting.
Air control system filter 382505 located in the handle
382480 should be replaced every 2000 drilling cycles
or when low air control system pressure is suspected.
Spindle threads should be blown clean and lubricated
every 100 drilling cycles.
DISASSEMBLY—DRILL HEAD:

gear pins and gears. Hold a large hex wrench or sim-
ilar tool on the side of the second reduction spider and
clamp in the vise. Heat the spider and bevel pinion to
approximately 300°F. Insert a suitable pin thru the hole
in the pinion 382461 and unscrew the pinion. Use
