care when evaluating problem tools.

BATTERY/CHARGER

• To reduce risk of injury, only charge Model BP20419 nickel cadmium batteries

with the Model BC20419 Charger. Other types of batteries may burst causing
personal injury and damage.

• Do not expose Charger to rain, snow or frost.

• Do not abuse the Charger line cord. Disconnect from receptacle by pulling the

plug rather than cord. Locate cord so that it will not be stepped on, tripped
over, or otherwise subjected to damage or stress.

• Do not use an extension cord unless absolutely necessary. Use of improper

extension cord could result in a risk of fire and electric shock. If an extension
cord must be used, make sure:

a) that blades on plug of extension cord are the same number, size and
shape as those of plug on charger
b) that extension cord is properly wired and in good electrical condition
c) that wire size is at least 16 gauge (AWG)

If the charger is used outdoors with an extension cord, the cord should be suit­able for outdoor use. Suitable cords are marked with "W" or "WA" on the jacket
and it is recommended that they be listed by the Underwriters Laboratories Inc.
(UL).

• Do not operate the Charger with a damaged line cord or plug – have these

replaced immediately.

-3-

• Do not operate the Charger if it has received a sharp blow, been dropped or
otherwise been damaged in any way. Do not disassemble the charger; refer to

BATTERY PACK OPERATION

CHARGING THE BA TTER Y PA CK

• IMPORTANT – Charge the battery packs before using for the first time since they are shipped in a par­tially charged condition. Two or three additional charges will be required before the battery packs are
fully conditioned and operating at full capacity.

• For best results charge the batteries in an ambient temperature between 40°F and 105°F.

• Batteries that have been used in the CRN38 for extended periods of time will become hot. If they are
hot when placed on the charger, the red charge indicator flashes until the battery cools to a tempera­ture that is safe for charging. This cool off time will depend on the battery and ambient temperatures
and can range from a few minutes to over 30 minutes. When the battery has cooled, the charger will
automatically switch to the Rapid Charge mode.

• Use care when installing and removing the battery from the tool, do not press the trigger or the tool
may activate. Be sure to first remove the battery from the CRN38 before cleaning the nose or remov­ing it for service.

STORAGE

• To get the longest battery life, ensure that the battery packs are discharged before being stored for
long periods (more than one month). Batteries can be stored in a dry location at any temperature
between –20°F and 120°F. They should be recharged before being used again.

BATTERY DISPOSAL

• Nickel cadmium batteries are recyclable and should be disposed of properly. Many state and local
laws make it illegal to dispose of these battery packs in normal trash or land fill
facilities. Recycle the batteries by dropping them off at local battery replacement
retailers or recycling centers. Look for the RBRC emblem.
Call 1-800-8-BATTERY for information about nickel cadmium battery recycling
and disposal.

Installation and Removal

• The battery is installed on the CRN38 Roofing Nailer by placing it on
the rails and sliding it forward until the latch engages.

• To remove, release the latch and at the same time slide the battery off
the rails.

TOOL OPERATION

EYE PROTECTION which conforms to ANSI specifications and provides protection
against flying particles both from the FRONT and SIDE should ALWAYS be worn by the
operator and others in the work area when loading, operating or servicing this tool. Eye
protection is required to guard against flying fasteners and debris, which could cause
severe eye injury.

The employer and/or user must ensure that proper eye protection is worn. Eye protec­tion equipment must conform to the requirements of the American National Standards
Institute, ANSI Z87.1-1989 and provide both frontal and side protection. NOTE: Non­side shielded spectacles and face shields alone do not provide adequate protection.

Battery Latch

• The CRN38 is a contact trip operated tool.

• For best operation hold the trigger in and press the tool against the work surface. Make sure to
push down until the tool stops against the work surface and turns off.

• The tool should be held perpendicular to the work surface or leaned back slightly.

• For best operation hold the tool as you would a screwdriver or drill dri­ver as shown.

• It is not necessary to push the tool hard, simply follow the nail down.
NOTE: Head damage and incomplete drives will result if the tool is
pushed hard.

• The tool will drive the nail quickly (less than .25 seconds). For opti­mum battery life push the tool down quickly.

The operator must not hold the trigger pulled except during fastening operation,
as serious injury could result if the trip accidentally contacted someone or
something, causing the tool to cycle.

Keep hands and body away from the discharge area of the tool.

COLD WEA THER OPERATION:

For cold weather operation, near and below freezing, the tool may slow down in operation and battery capacity
will be reduced.

Do not store tools in a cold weather environment to prevent frost or ice formation on
the tools operating mechanisms that could cause tool failure.

ENERGY ADJUSTMENT/FASTENER DEPTH CONTROL

• Fastener drive depth adjustment is accomplished by rotating the
adjustment wheel of the Energy Management System.

• Rotate the wheel counterclockwise for deeper drives, clockwise for
less depth.

• Thicker layers of shingles generally require more depth of drive.

• Unless the shingles are hot the tool can typically be used at the
maximum setting without overdriving and damaging the shingles.

• To optimize the number of fasteners per charge, adjust the energy
management system so the driven nails are flush with the shingle sur­face on the lowest setting possible.

TOOL OPERATION CHECK

Remove all fasteners from tool before performing tool operation check.

Contact T rip OPERA TED T OOL:

With finger off the trigger, press the contact trip against the work surface.

THE TOOL MUST NOT CYCLE.

Adjusting Wheel

CHARGER OPERATION

NORMAL CHARGING:

• Plug the charger into a 120V AC outlet. Insert the battery pack onto
the charger ramp; press firmly to seat completely. The red indicator will
begin to flash and after a few seconds will light continuously. When the
charge is complete, the red indicator will go off and the green indicator
will come on. The battery pack can now be removed and installed in the
tool.

• Charge battery packs in a well-ventilated area. The charger housing has several ventilation openings.
These must remain open for proper charger operation. Do not obstruct these openings or place
charger on any surface that will block air from flowing through the charger housing. Do not cover the
charger or battery with a cloth or other cover while charging.

• The battery can be left on the charger after full charge has been reached. The battery will continue to
be charged at a low, trickle rate.

• If the CRN38 and battery packs are not going to be used within a week, battery life will be extended by
taking them off the charger. Recharge the battery packs before using again.

• Normal charging time is between 10 and 60 minutes. This will vary depending on the charge that is
needed. If the battery has only been partially discharged, the full 60-minute charge will not be
required.

• It is normal for the charger to hum and become warm to the touch during charging, this does not indi­cate a problem.

FUNCTION OF CHARGER INDICATORS

• Flashing Red Indicator – when the battery pack is first placed on charger, it is being analyzed before
starting the Rapid Charge mode. Normally the indicator will change to steady red after a few sec­onds, showing that rapid charging has begun. However, if the indicator continues flashing, the battery
pack may be too hot or may have been over discharged. Battery pack condition will be monitored and
the charger will switch to the Rapid Charge mode when ready. At that time, the steady red indicator
will be seen.

• Steady Red Indicator – the battery pack is in the Rapid Charge mode. Depending on the battery
pack condition, the charge mode will normally last up to one hour.

• Steady Green Indicator – the Rapid Charge mode has ended and the battery pack can be removed
for use in the tool. The battery pack can also be left in the charger and a small Trickle Charge current
will keep the battery pack fully charged.

SHINGLE GUIDE

SHINGLE GUIDE ADJUSTMENT

• Loosen locking screw using the 3mm wrench.

• Slide the guide to set the desired exposure 5" - 6 1/2"

• For longer exposure, remove the guide and reverse it.

• Tighten the locking screw.

CLEANING THE CORDLESS NAILER

Do not use gasoline or similar highly flammable liquids to clean
the nailer. Vapor could be ignited by a spark causing an explosion.

For best operation clean system as follows:

Tar and dirt may build up on the nose, driver, and feed system. This
can prevent correct operation. Remove any buildup with kerosene,
#2 fuel oil or diesel fuel. Do not dunk the nailer into these solvents
beyond the height of the nail heads. Dry off the nailer before use.
Any oil film left after cleanup will accelerate the tar buildup, and the
nailer will require more frequent re-cleaning.

NOTE: Solvents sprayed on the nose driver and feed system
may have the opposite effect! The solvent may soften the tar on
the shingles and cause tar buildup to be accelerated. Dry
operation is better, as noted above.

Cleaning of tar from nose assembly and driver

Depress nose release button, and pull nose from tool.
Nose can be wiped down, or immersed in cleaning solvent. Clean the end
of the driver as well as the nose assembly. The driver guide may need
to be removed from the nose in order to clean it properly. Do not immerse
tool in cleaning solvents. Instead, apply a light coat of oil to the nail feed
roller. Tool exterior can be wiped down with cleaning solvents. Once clean
insert nose assembly into tool. Make sure D shaped driver is properly
aligned to nose. Push nose into tool until it locks in place. Review
the nose control switch and verify that it cycles correctly.

MAINTAINING THE CORDLESS TOOL

When working on cordless tools, note the warnings in this manual
and use extra care evaluating problem tools.

Replacing motor brushes:

Remove screws from either side of brush cover and pull brush cover down
to remove it from the motor area of the tool. Remove the brush retaining
springs from the motor. Remove the quick disconnects from the control
module, remove the brush retaining springs, and remove the brushes.
Be careful when removing brush springs as they may fly off and become
lost or stuck in motor.

Installation is the reverse of removal.

REPLACEMENT PARTS:

STANLEY-BOSTITCH replacement parts are recommended. Do not use modified parts or parts which
will not give equivalent performance to the original equipment.

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.

Lubricating the o-rings is recommended on a yearly basis for a normally used tool. Heavy usage may
warrant more frequent greasing intervals. See your authorized Bostitch dealer or service center for
o-ring service information.
