Avoid the risk of severe electrical shock by checking for live electrical wires that
may be hidden by walls, floors or ceilings. Turn off the breaker switch to ensure
there are no live wires.
26. HOSES.
Air hoses should be professional grade and have a minimum of 150 psi working
pressure. Make sure that the hose is securely fastened. If there is any damage to
the hose, replace it before using the nailer.
27. PLACE NAILER PROPERLY ON WORK PIECE.
Do not drive fasteners on top of other fasteners or with the nailer at too steep of
an angle. The fasteners can ricochet and hurt someone.
28. BE CAREFUL OF DOUBLE FIRING DUE TO RECOIL.
If the safety/push lever is unintentionally allowed to re-contact the work piece
following recoil, an unwanted fastener will be driven.
In order to avoid this undesirable double fire:
Intermittent operation ﹙trigger or single firing﹚
(not available on all models)
1﹚ Set the switching device to SINGLE ACTUATION MECHANISM.
2﹚ Pull the trigger rapidly and firmly.
Continuous operation﹙safety/push lever firing﹚
1﹚ Do not press the nailer against the wood with excessive force.
2﹚ Separate the nailer from the wood as it recoils after fastening.
29. DO NOT DRIVE FASTENERS CLOSE TO THE EDGE OR CORNER OF THE
WORK ESPECIALLY WHEN USING THIN MATERIAL.
The work piece is likely to split and the fastener could fly free and hit someone.
30. NEVER DRIVE FASTENERS FROM BOTH SIDES OF A WALL AT THE SAME
TIME.
The fasteners could be driven into and through the wall and hit a person on the
opposite side.
31. DO NOT DISCONNECT AIR HOSE FROM NAILER WHILE FINGER IS ON
THE TRIGGER.
The nailer can fire when it is re-connected to an air supply.

3. Air Hose
Air hose must have a minimum working pressure rating of 150 psi or 150% of the
maximum pressure produced in the system, whichever is higher.
Operating Pressure
Recommended operating pressure range is 70 to 120 psi / 5 to 8.5 kgs.
Maximum permissible operating pressure is 150 psi.
Select the operating pressure within this range for the best fastener
performance. The nail length and thickness and the hardness of the wood
are factors in determining what the pressure should be set at.
Do not exceed this recommended operating pressure.
Lubrication
It is important that the tool be properly lubricated. Without proper lubrication, the tool
will not work properly and parts will wear prematurely.
Use INTERCHANGE pneumatic tool lubricant. Do not use detergent oil or
additives. These lubricants will harm the O-rings and other rubber parts. This
will cause the tool to malfunction.
Filter-regulator-lubricator units should always be used. Keep the lubricator
filled with INTERCHANGE pneumatic tool lubricant.
If a lubricator is not available, supply 3 to 5 drops of INTERCHANGE
pneumatic tool lubricant into the air plug on the tool twice a day.
NOTE: Dirt and water in the air supply are major causes of wear in the tool. An air
filter will help to get the best performance and minimum wear from the tool.
Frequent, but not excessive, lubrication is required for the best performance. Oil added
through the air line connection will lubricate the internal parts.

CN90-15 Coil NailerDB
Limited Five (5) Year Warranty for
Pneumatic Nailers
Our products are designed and constructed using the highest standards of both mate-
rial and workmanship. We warrant to the original retail purchaser that their nailers will
be free from defects in material or workmanship for the warranty period of five years.
During the warranty period (which begins on the purchase date), we will repair or
replace, at our option and expense, any product or part that is defective in materials or
workmanship after examination by an Authorized Warranty Service Center, subject to the
exceptions, exclusions and limitations described below. Any replacement product or part
will carry a warranty for the balance of the warranty period applicable to the replaced
product or part. A DATED SALES RECEIPT OR PROOF OF PURCHASE FROM THE
ORIGINAL RETAIL PURCHASER IS REQUIRED TO MAKE A WARRANTY CLAIM. To make
a warranty claim, you must return the product, with proper receipt/proof of purchase
and return transportation charges prepaid, to us (your dealer) or an Authorized Warranty
Service Center. We will perform our obligations under this warranty within a reasonable
time after approval of the warranty claim.
WARRANTY EXCLUSIONS
The following warranty exclusions apply:
1. Normal wear parts are not covered under this warranty. Normal wear parts
include, for example, rubber o-rings, seals and driver blades.
2. This warranty does not cover parts damaged due to normal wear, misapplica-
tion, misuse, accidents, operation at other than recommended speeds, improper
storage, or damage resulting during shipping.
3. Products used in production/industrial applications are excluded from this war-
ranty.
4. Labor charges, maintenance, or loss, damage and repairs resulting from im-
proper operation are not covered by this warranty.
GENERAL WARRANTY CONDITIONS
This warranty will be honored, only if:
1. Clean, dry, regulated compressed air has been used at air pressure not exceed-
ing the maximum indicated on the tool casting;
2. No evidence of abuse, abnormal conditions, accident, neglect, misuse or im-
proper modifications or storage of the product exists; and
3. No deviations from following recommended operating instructions, specifi-
cations, and maintenance schedules exist. (Read Operator Manual for use,
specifications, and maintenance instructions).
This warranty is the only warranty for the product and we disclaim all other warran-
ties. Any implied warranties will be limited in duration to the applicable warranty period
specified above. Some states do not allow limitations on how long an implied war-
ranty lasts, so the above limitation may not apply to you. Your remedies are solely and
exclusively as stated above. We shall in no event be liable for incidental, consequential,
indirect or special damages. Some states do not allow the exclusion or limitation of
incidental or consequential damages, so the above limitation or exclusion may not apply
to you. In no event, whether as a result of a breach of contract, warranty, tort (including
negligence) or otherwise, shall our liability exceed the price of the product that has given
rise to the claim or liability. Any liability connected with the use of this product shall
terminate upon the expiration of the warranty period specified above. No employee or
representative of any distributor or dealer is authorized to make any change or modifica-
tion to this warranty.
This warranty gives you specific legal rights, and you may also have other rights,
which vary from state to state.
