1. To drive a nail, you may place the contact element
against the workpiece and pull the trigger, or
(Fig. 14 & 15)
2. Pull the trigger first and then place the contact element
against the workpiece.
• No. 1 method is for intermittent nailing, when you wish
to drive a nail carefully and very accurately. No. 2
method is for continuous nailing.
CAUTION:
• However when the tool is set to the "Intermittent
Nailing" mode, WITH THE TRIGGER HELD IN A
HALF-PULLED POSITION, an unexpected nailing
could occur, if contact element is allowed to re-contact
against the workpiece or the other surface under the
influence of recoil. In order to avoid this unexpected
nailing, perform as follows;
- A. Do not place the contact element against the
workpiece with excessive force.
- B. Pull the trigger fully and hold it on for 1-2 seconds
after nailing.
• For No. (1) method, set the change lever to the
position.
For No. (2) method, set the change lever to the
position.
After using the change lever to change the nailing
method, always make sure that the change lever is
properly set to the position for the desired nailing
method. (Fig. 16 & 17)
MAINTENANCE
CAUTION:
• Always disconnect the air hose from the tool before
attempting to perform inspection or maintenance.
Jammed nailer (Fig. 18)
CAUTION:
• Always disconnect the air hose and remove the nails
from the magazine before cleaning a jam.
When the nailer becomes jammed, do as follows:
Open the magazine cap and remove the nail coil. Insert a
small rod or the like into the ejection port and tap it with a
hammer to drive out the nail jamming from the ejection
port. Reset the nail coil and close the magazine cap.
Cleaning and removal of tar and dirt
Adhesion of tar and dirt to areas around the contact
element will prevent smooth movement of the contact
element (safety mechanism). Causing accidental
discharge. Periodically clean the areas around the contact
element. Use a solvent such as kerosene, #2 fuel oil or
diesel fuel.
Immerse only the contact element and the areas around
the ejection port in solvent and remove tar and dirt with
brush. Always wear waterproof gloves to protect your
hands. Never immerse the housing, magazine, etc. in
solvent. Malfunction of the tool may result. Always
dispose of the solvent used in a safe and prudent manner
and in compliance with all local and national code
requirement. (Fig. 19)
Dry off the tool before use. Any oil film left after cleanup
will accelerate the tar buildup, and the tool will require
more frequent recleaning. After drying off the tool, oil the
moving parts to prevent rusting and to assure good
lubrication and operation or moving parts.
WARNING:
• Never use gasoline or other similar highly volatile
liquids for cleaning. Vapors of such liquids may enter
the tool and could be ignited by sparks produced during
nailing and cause an explosion.
Drain tool
Remove the hose from the tool. Place the tool so that the
air fitting faces down to the floor. Drain as much as
possible.
Cleaning of tool
Iron dust that adhere to the magnet can be blown off by
using an air duster.
Cap
When not in use, disconnect the hose. Then cap the air
fitting with the cap. (Fig. 20)
Storage
When not in use, the nailer should be stored in a warm
and dry place.
Maintenance of compressor, air set and air hose.
(FIg. 21 & 22)
After operation, always drain the compressor tank and the
air filter. If moisture is allowed to enter the tool, It may
result in poor performance and possible tool failure.
Check regularly to see if there is sufficient pneumatic oil in
the oiler of the air set. Failure to maintain sufficient
lubrication will cause O-rings to wear quickly. (Fig. 23)
Keep the air hose away from heat (over 60°C, over
140°F), away from chemicals (thinner, strong acids or
alkalis). Also, route the hose away from obstacles which it
may become dangerously caught on during operation.
Hoses must also be directed away from sharp edges and
areas which may lead to damage or abrasion to the hose.
(Fig. 24)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
