Tool Maintenance
The 212 requires a minimum amount of mainte-
nance. Regular inspection and correction of
minor problems will keep the tool operating effi-
ciently and prevent downtime.
If a filter-regulator-lubricator unit is not being
used in the air supply:
(1) Remove hose fitting from air inlet connector
and drop in a few drops of automatic trans-
mission fluid or light oil.
(2) Blow out air line to remove dirt and water
before connecting air hose to tool.
At regular intervals, depending upon use,
replace all seals in tool. Service Kits should be
kept on hand. (See SPARE PARTS AND SERV-
ICE KIT; NOTES.) Inspect both hydraulic
pistons, and their piston rods for scored
surfaces, excessive wear or damage, and
replace as necessary.
CAUTION: Always replace seals and back-up
rings when tool is disassembled for any rea-
son.
Nose Assembly Maintenance
To extend jaw life: Disassemble nose assembly
periodically; clean and inspect components - -
use a pick to clean jaw grooves. CAUTION:
Wash pads in mineral spirits or isopropyl
alcohol ONLY. Dry O-rings; urethane jaw
assemblies IMMEDIATELY after cleaning as pro-
longed contact with solvent causes swelling - -
dry other parts.
In nose assemblies without UNITIZED
TM
jaws,

alcohol, or other suitable solvent, to clean jaws
and wash away metal chips and dirt. If more
thorough cleaning or maintenance is necessary,

particles packed in jaw grooves. Reassemble per
instructions on applicable NOSE ASSEMBLY
