Maintenance; Cold Weather Operation; General Maintenance - Ryobi YN250SFD Manual Del Operador

WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields or goggles
marked to comply with ANSI Z87.1. Failure to do so could
result in fluids entering your eyes resulting in possible
serious injury.
WARNING:
Disconnect the tool from the air supply before perform-
ing maintenance. Failure to do so could result in serious
personal injury.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.

MAINTENANCE

LUBRICATION
Frequent, but not excessive, lubrication is required for
best performance. Oil for pneumatic fastening tools added
through the air line connection will lubricate the internal parts.
Do not use detergent oil or additives as these lubricants will
cause accelerated wear to the seals and bumpers in the
tool, resulting in poor tool performance and frequent tool
maintenance.

COLD WEATHER OPERATION

For cold weather operation, near and below freezing, the
moisture in the air line may freeze and prevent tool operation.
We recommend the use of air tool lubricant or permanent
antifreeze (ethylene glycol) as a cold weather lubricant.
Do not store tools in a cold weather environment to pre-
vent frost or ice formation on the tools' operating valves
and mechanisms that could cause tool failure and pos-
sible injury.
NOTE: Some commercial air line drying liquids are harmful
to "O" rings and seals. Do not use these low temperature
air dryers without checking compatibility.
AIR SUPPLY PRESSURE AND VOLUME
Air volume is as important as air pressure. The air volume
supplied to the tool may be inadequate because of under-
size fittings and hoses, or from the effects of dirt and water
in the system. Restricted air flow will prevent the tool from
receiving an adequate volume of air, even though the pres-
sure reading is high. The results will be a slow operation or
reduced driving power. Before evaluating tool problems for
these symptoms, trace the air supply from the tool to the
supply source for restrictive connectors, low points contain-
ing water and anything else that would prevent full volume
flow of air to the tool.
