Lubrication; Cold Weather Care - Hitachi NT50AF Manual De Instrucciones Y Seguridad

English

LUBRICATION

Frequent, but not excessive, lubrication is required for best perfor‑
mance. Oil added through the air line connection will lubricate the
internal parts. Use Pneumatic Tool Lubricant, Mobil Velocite #10, or
equivalent. Do not use detergent oil or additives as these lubricants
will cause accelerated wear to the seals and Piston Cushion in the
Tool, resulting in poor tool performance and frequent Tool mainte‑
nance.
If no airline lubricator is used, add oil during use into the air fitting
on the Tool once or twice a day. Only a few drops of oil at a time
are necessary. Too much oil will only collect inside the Tool and will
be noticeable in the exhaust cycle.

COLD WEATHER CARE

For cold weather operation, near and below freezing, the moisture
in the air line may freeze and prevent Tool operation. We recom‑
mend the use of WINTER FORMULA air tool lubricant (NEW‑MATIC
Winter Formula or equivalent) or permanent anti freeze (ethylene
glycol) as a cold weather lubricant.
CAUTION: Do not store tools in a cold weather environment to
prevent frost or ice formation on the tools operating valves and
mechanisms that could cause tool failure.
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.
CAUTION
Do not operate the Tool at high pressure without fasteners
