Bostitch BT1855SP-A, Safety And Operating Instructions Manual

LUBRICATION 

•  Frequent, but not excessive lubrication is required for best performance. Oil added through the air line 

connection will lubricate the internal parts. For details of the correct lubricant see the Tool Technical Data. 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.

•  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 (3-5) at a time are necessary. Too much oil will only collect inside the tool and will be noticeable in 
the exhaust cycle.

•  Cold weather operation. - For cold weather operation, near and below freezing, the moisture in the air line may 

freeze and prevent the tool operation. We recommend the use of BOSTITCH Winter Formula air tool lubricant 
or permanent antifreeze (ethylene glycol) as a cold weather lubricant.

Caution

 - To prevent frost or ice formation on the tool’s operating valves and mechanisms that could cause tool 

failure, do not store the tool in a cold weather environment.

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.
