Firing modes
Testing the nailer
Potential hazard that may result in moderate injury or
damage to equipment.
WARNING!
Keep your finger off the trigger except when nailing. Serious
injury could result if the push lever accidentally contacts you or
others in work area.
Keep hands and body away from the discharge area. This
Mastercraft
®
nailer may bounce from the recoil of driving a nail
and unexpectedly drive another nail, possibly causing injury.
Some types of loaded nails can spark out of the muzzle during
a nail driving operation. Exercise caution!
WARNING!
The Mastercraft® Air-powered Coiled Roofing Nailer has two firing modes: sequential fire for single firing,
or bump fire for repetitive, fast firing of nails. The bump fire trigger kit comes installed on the nailer, and
the sequential fire trigger kit is included as replacement parts. See page 18 for instructions on how to
change from one mode to the other.
1. Sequential fire (single shot)
① Position the nail outlet on the workpiece with finger
off the trigger.
② Push the nailer down until the push lever is
completely depressed.
③ Pull the trigger to drive a nail.
④ Remove finger from the trigger.
⑤ To drive another nail, move the nailer along the
workpiece, repeating steps 1 to 4 as required (Fig. J).
2. Bump fire (multiple shots)
① Pull the trigger with the nailer off the workpiece.
② Drive a nail by pressing the nailer against the
workpiece to depress the push lever.
③ Drive additional nails by moving the nailer along
the workpiece with a bouncing motion. Each
depression of the push lever will drive a nail.
When the required nails have been driven,
remove finger from the trigger (Fig. K).
