COLDWEATHEROPERATION
CAUTION: Do not store in cold environment. Frost or ice
could form inside tool affecting operation and damaging tool.
Use a cold temperature lubricant, such as ethylene glycol,
when operating tool in freezing temperatures.
Refer to Figure 10.
LUBRICATION
Lubricate tool dally with quality air tool oil. If no air line lubri-
cator is used, place five or six drops of oil into air inlet cap
(Figure 10, Key No. 57) of tool everyday.
MAGAZINE AND PISTON-RAM
• Keep magazine and nose of tool clean and free of any dirt,
lint or abrasive particles.
The tip of the ram (Figure 10, Key No. 16) can become
dented or rounded over time.
• Square off the tip of the ram with a clean, fine hand file to
extend the life of the ram and tool. Fastener firing will be
more consistent if the ram tip is kept clean and square.
SAFETY MECHANISM CHECK
Inspect contact trip safety mechanism dally for proper opera-
tion. Do not operate tool if mechanism is not operating
properly.
With the red push-button switch in the rapid-fire mode, per-
form the following procedures to test safety mechanism:
• Leave trigger untouched wNe pushing contact trip into
workpiece. Tool must not fire.
• Pull trigger wNe contact trip is clear of work and pointed
away from operator and others. Tool must not fire.
• Depress and hold trigger. Push contact trip against work
where fastener is needed. The tool should drive only one
fastener each time the contact tdp is pushed against
workpiece.
If contact trip mechanism does not operate properly,
repair tool immediately through Sears Service Center.
Replace any damaged or missing parts. Use the parts list to
order parts.
REBUILD KITS
Rebuild kits are available as spare parts, (see page 9). Tools
should be rebuilt if tool fails to operate properly after extended
use. See troubleshooting to determine required replacement
parts.
Disconnect tool from air supply before attempting repair
or adjustment.
NOTE: When replacing O-rings or cylinder, lubricate with
grease before assembly.
