Cold Weather Precautions; Corrective Action - ITW DUO-FAST HT-755 Classic Manual De Instrucciones De Operacion Y Seguridad

COLD WEATHER PRECAUTIONS

FOLLOW THE RECOMMENDATIONS BELOW WHEN USING THE TOOL AT TEMPERATURES BELOW FREEZING:
• Keep tool as warm as possible until you are ready to use it.
• Remove fasteners from tool.
• Reduce air pressure to below 80 PSIG (pounds per square inch).
• Cycle tool to allow oil and ethylene glycol to lubricate O-rings.
• Increase air pressure to minimum required by tool.
• Load fasteners and adjust air pressure until fasteners are driven properly.
OTHER RECOMMENDATIONS FOR USING THE TOOL IN COLD TEMPERATURES:
• Fill air line lubricators with ethylene glycol automotive-type antifreeze (non- sealant type).
• Lubricate tool at least once a day with a S.A.E. No. 10 non-detergent oil.
• Drain moisture from air compressor tank daily.
MALFUNCTIONS
Be alert for tool problems. A malfunctioning tool must be immediately withdrawn from use and not used again
until it has been repaired by a qualified service representative.
Operating a tool with the following malfunctions is dangerous and unsafe. The list is representative only, not all
inclusive.
• Work contact element that sticks or binds along it's vertical path of travel.
• Trigger sticks or binds.
• Air leaks from the tool. Some air leaks affect safety. Others do not. Be safe and assume all air leaks
affect safety. Stop using the tool immediately and have it repaired.
TROUBLESHOOTING
PROBLEM
• Fasteners will not drive completely into wood. • Increase air pressure (do not exceed 120 psi).
• Fasteners penetrate properly during normal
operation, but won't drive fully at faster speeds.
• Fasteners drive too deeply into wood.
• Fastener jams in nose of tool.
• Tool skips during operation - no fasteners are
driven from time-to-time.
• Tool operates, but no fasteners are driven.
• Air leaks at cap when tool is connected to air.

CORRECTIVE ACTION

• Increase air flow to tool - use larger air lines (3/8 inch ID
minimum).
• Reduce air pressure.
• STAPLERS: Open magazine and clear jammed fastener.
• NAILERS: Push driver blade back into tool. Then clear
jammed nail out of nose.
• Check magazine for proper fasteners. Magazine pusher
should slide freely. Clean as needed to remove debris.
• Make sure correct fasteners are being used. Use fasteners
that meet DUO-FAST specifications only.
• Increase air flow to tool - use larger air lines (3/8 ID
minimum).
• Check magazine for debris or jammed fastener.
• Check for correct fastener in tool.
• Check air pressure, make sure suggested air pressure is
used for full cycle of tool.
• Look for damage to the pusher and/or the pusher spring.
• Tighten cap screws.
