Firing modes
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

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!
To avoid double firing or accidental firing due to recoil. Do not press
the nailer against the wood with excessive force. Separate the nailer
from wood as it recoils after nailing.
1. Single Sequential fire (single shot)
①
Push the switching device close to the trigger
completely as shown in the diagram. Otherwise,
it will be set to contact actuation mechanism.
②
Position the nail outlet on the workpiece with
finger off the trigger.
③
Push the nailer down until the push lever is
completely depressed.
④
Pull the trigger to drive a nail.
○
5
Remove finger from the trigger.
⑥
To drive another nail, move the nailer along the
workpiece, repeating steps 2 to 5 as required
(Fig. J).
2. Contact actuation (multiple shots)
①
Pull the switching device away from the trigger
until the hole is visible as shown in the diagram.
Otherwise, it will be set to single firing mechanism.
②
Pull the trigger with the nailer off the workpiece.
③
Drive a nail by pressing the nailer against the
workpiece to depress the push lever.
④
Drive additional nails by moving the nailer along
the workpiece with a bouncing motion.
⑤
Each depression of the push lever will drive a nail.
When the required nails have been driven,
remove finger from the trigger (Fig. K).
The Mastercraft
®
Air-powered Coil Framing Nailer has two firing modes: sequential fire for single
firing, or bump fire for repetitive, fast firing of nails.
This nailer is equipped with a push lever at the nailing point and will not operate unless the push lever is
depressed (pushed upwards). Each mode requires a different method of operation:
Single sequential actuation mechanism:
First, press the push lever against the wood; next, pull the
trigger to drive the nail. After nailing once, nailing will not be possible again until the trigger is released
and pressed again.
Contact actuation mechanism:
First, press the push lever against the wood; next, pull the trigger to drive
the nail. Or pull the trigger; next, press the push lever against the wood to drive the nail. If the trigger is
held back, a nail will be driven each time the push lever is pressed against the wood.

NOTE
:
The single sequential actuation mechanism is for use where precision
fastener placement is desired. It may reduce the possibility of bodily injury to
you or others in the work area compared to the bump actuation as it is less
likely to drive an unwanted nail if you keep the trigger pulled and
accidentally bump the push lever against yourself or others.
The single sequential actuation mechanism may also reduce the speed of
operation compared the bump firing and is recommended for inexperienced
users.
Both bump and sequential fire are safe if used as described above
and according to all warnings and instructions.
Always handle nails and package carefully. If nails are dropped, collating
wire may be broken.
After nailing: disconnect air hose from the nailer, remove all nails from the
nailer, add 5-10 drops of pneumatic tool lubricant into the air plug, and open
the petcock on the air compressor tank to drain any moisture.
