Refer to Figure 7 (page 8).
LUBRICATION
Lubricate nailer daily with quality air tool oil. If no air line lubri-
cator is used, place five or six drops of oil into air inlet cap
(Fig. 7, No. 24) of tool everyday.
MAGAZINE AND PISTON/RAM
• Keep magazine and contact trip area clean and free of any
dirt, lint or abrasive particles.
The tip of the ram (Fig. 7, 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
Refer to Figure 4.
Inspect contact trip safety mechanism daily for proper opera-
tion. Do not operate tool if mechanism is not operating properly.
With the switch (Fig. 7, No. 43) set to the single-fire mode, per-
form the following procedures to test the safety mechanism:
° Leave trigger untouched while pushing contact trip into
workpiece. Tool must not fire.
° Pull trigger while contact trip is clear of work and pointed
away from operator and others. Tool must not fire.
° Push contact trip against work where fastener is needed
and flick trigger. The tool should drive only one fastener
each time the contact trip is pushed against workpiece and
trigger is flicked.
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 air
tool oil before assembly.
