MAINTAINING THE PNEUMATIC TOOL

When working on air tools, note the warnings in this manual and use extra care
evaluating problem tools.
CAUTION: Pusher spring (constant force spring). Caution must be used when working with the spring
assembly. The spring is wrapped around, but not attached to, a roller. If the spring is extended beyond
its length, the end will come off the roller and the spring will roll up with a snap, with a chance of
pinching your hand. Also the edges of the spring are very thin and could cut. Care must also be taken
to insure no permanent kinks are put in the spring as this will reduce the springs force.
REPLACEMENT PARTS:
STANLEY replacement parts are recommended. Do not use modified parts or parts which will not give
equivalent performance to the original equipment.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker "O"-LUBE or
equivalent on all "O"-rings. Coat each "O"-ring with "O"-LUBE before assembling. Use a small amount of oil
on all moving surfaces and pivots. After reassembly add a few drops of Air Tool Lubricant through the air line
fitting before testing.
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 undersize 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 pressure reading is high. The
results will be slow operation, misfeeds 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, swivel fittings,
low points containing water and anything else that would prevent full volume flow of air to the tool.

DEPTH ADJUSTMENT

Always disconnect air supply: 1. Before making adjustments; 2. When servicing
the tool; 3. When clearing a jam; 4. When tool is not in use; 5. When moving to a
different work area, as accidental actuation may occur, possibly causing injury.
SB1850BN FASTENER CONTROL ADJUSTMENT
The Fastener Control adjustment feature provides close control of the fastener drive depth; from flush
with the work surface to shallow or deep countersink. First, set the air pressure for consistent drive in the
specific work. Then use the Fastener Control adjustment to give the desired depth of drive.
TO ADJUST FASTENER CONTROL ADJUSTMENT:
1. With air pressure set, drive a few fasteners into a representative material sample to
determine if adjustment is necessary.
2. If adjustment is required, disconnnect air supply.
