Face shield

WARNING:

It is an employer’s responsibility to enforce the use of safety eye protection equipment by the tool operators and by other persons in the immediate working area.

• Wear hearing protection to protect your ears against exhaust noise and head protection. Also wear light but not loose clothing. Sleeves should be buttoned or rolled up. No necktie should be worn.

• Rushing the job or forcing the tool is dangerous.

Handle the tool carefully. Do not operate when under the influence of alcohol, drugs or the like.

• General Tool Handling Guidelines:

1.

Always assume that the tool contains fasteners.

2.

Do not point the tool toward yourself or anyone whether it contains fasteners or not.

3.

Do not activate the tool unless the tool is placed firmly against the workpiece.

4.

Respect the tool as a working implement.

5.

No horseplay.

6.

Do not hold or carry the tool with a finger on the trigger.

7.

Do not load the tool with fasteners when any one of the operating controls is activated.

8.

Do not operate the tool with any power source other than that specified in the tool operating/safety instructions.

•

•

•

•

•

•

The area should be sufficiently illuminated to assure safe operations. The area should be clear and litter-free. Be especially careful to maintain good footing and balance.

Only those involved in the work should be in the vicinity. Children especially must be kept away at all times.

There may be local regulations concerning noise which must be complied with by keeping noise levels within prescribed limits. In certain cases, shutters should be used to contain noise.

Do not play with the contact element: it prevents accidental discharge, so it must be kept on and not removed. Securing the trigger in the ON position is also very dangerous. Never attempt to fasten the trigger. Do not operate a tool if any portion of the tool operating controls is inoperable, disconnected, altered, or not working properly.

Operate the tool within the specified air pressure of 0.44 - 0.83 MPa (4.4 - 8.3 bar) for safety and longer tool life. Do not exceed the recommended max. operating pressure of 0.83 MPa

(8.3 bar). The tool should not be connected to a source whose pressure potentially exceeds 1.37

MPa (13.7 bar).

Make sure that the pressure supplied by the compressed air system does not exceed the maximum allowable pressure of the fastener driving tool. Set the air pressure initially to the lower value of the recommended allowable pressure (see SPECIFICATIONS).

Never use the tool with other than compressed air. If bottled gas (carbon dioxide, oxygen, nitrogen, hydrogen, air, etc.) or combustible gas

(hydrogen, propane, acetylene, etc.) is used as a power source for this tool, the tool will explode and cause serious injury.

3

• Always check the tool for its overall condition and loose screws before operation. Tighten as required.

• Make sure all safety systems are in working order before operation. The tool must not operate if only the trigger is pulled or if only the contact arm is pressed against the wood. It must work only when both actions are performed.

Test for possible faulty operation with nails unloaded and the pusher in fully pulled position.

• Make sure that the trigger is locked when the change lever is set to the LOCK position.

• Check walls, ceilings, floors, roofing and the like carefully to avoid possible electrical shock, gas leakage, explosions, etc. caused by striking live wires, conduits or gas pipes.

• Use only nails specified in this manual. The use of any other nails may cause malfunction of the tool.

• Never use fastener driving tools marked with the symbol “Do not use on scaffoldings, ladders” for specific application for example:

when changing one driving location to another involves the use of scaffoldings, stairs, ladders, or ladder alike constructions, e.g. roof laths;

-

closing boxes or crates; fitting transportation safety systems e.g. on vehicles and wagons.

• Do not permit those uninstructed to use the tool.

• Make sure no one is nearby before nailing.

Never attempt to nail from both the inside and outside at the same time. Nails may rip through and/or fly off, presenting a grave danger.

• Watch your footing and maintain your balance with the tool. Make sure there is no one below when working in high locations, and secure the air hose to prevent danger if there is sudden jerking or catching.

• On rooftops and other high locations, nail as you move forward. It is easy to lose your footing if you nail while inching backward. When nailing against perpendicular surface, nail from the top to the bottom. You can perform nailing operations with less fatigue by doing so.

• A nail will be bent or the tool can become jammed if you mistakenly nail on top of another nail or strike a knot in the wood. The nail may be

•

•

•

•

• thrown and hit someone, or the tool itself can react dangerously. Place the nails with care.

Do not leave the loaded tool or the air compressor under pressure for a long time out in the sun. Be sure that dust, sand, chips and foreign matter will not enter the tool in the place where you leave it setting.

Do not point the ejection port at anyone in the vicinity. Keep hands and feet away from the ejection port area.

When the air hose is connected, do not carry the tool with your finger on the trigger or hand it to someone in this condition. Accidental firing can be extremely dangerous.

Handle the tool carefully, as there is high pressure inside the tool that can be dangerous if a crack is caused by rough handling (dropping or striking). Do not attempt to carve or engrave on the tool.

Stop nailing operations immediately if you notice something wrong or out of the ordinary with the tool.

Always disconnect the air hose and remove all of the nails:

1.

When unattended.

2.

Before performing any maintenance or repair.

3.

Before cleaning a jam.

4.

Before moving the tool to a new location.

Perform cleaning and maintenance right after finishing the job. Keep the tool in tip-top condition. Lubricate moving parts to prevent rusting and minimize friction-related wear. Wipe off all dust from the parts.

When not operating the tool, always lock the trigger by turning the change lever to the LOCK position.

Do not operate this tool if it does not contain a legible WARNING LABEL.

Do not modify tool without authorization from

Makita.

Ask Makita’s Authorized service centers for periodical inspection of the tool.

To maintain product SAFETY and RELIABILITY, maintenance and repairs should be performed by Makita Authorized Service Centers, always using Makita replacement parts.

Selecting compressor

• Select a compressor that has ample pressure and air output to assure cost-efficient operation. The graph shows the relation between nailing frequency, applicable pressure and compressor air output. Thus, for example, if nailing takes place at a rate of approximately 40 times per minute at a compression of 0.59 MPa (5.9 bar), a compressor with an air output over 3 CFM (ft 3 /minute) is required. Pressure regulators must be used to limit air pressure to the rated pressure of the tool where air supply pressure exceeds the tool’s rated pressure. Failure to do so may result in serious injury to tool operator or persons in the vicinity.

Selecting air hose

• Use an air hose as large and as short as possible to assure continuous, efficient nailing operation. With an air pressure of 0.49 MPa (4.9 bar), an air hose with an internal diameter of over 8.5 mm (5/16”) and a length of less than 20 m (6.6 ft.) is recommended when the interval between each nailing is 0.5 seconds. Air supply hoses shall have a minimum working pressure rating of 1.03 MPa (10.3 bar) or 150 percent of the maximum pressure produced in the system whichever is higher.

CAUTION:

• Low air output of the compressor, or a long or smaller diameter air hose in relation to the nailing frequency may cause a decrease in the driving capability of the tool.

Lubrication

• To insure maximum performance, install an air set (oiler, regulator, air filter) as close as possible to the tool. Adjust the oiler so that one drop of oil will be provided for every 30 nails.

004296

• When an air set is not used, oil the tool with pneumatic tool oil by placing

2 (two) or 3 (three) drops into the air fitting. This should be done before and after use. For proper lubrication, the tool must be fired a couple of times after pneumatic tool oil is introduced.

ASSEMBLY

004299

• To adjust the depth of nailing, turn the adjuster so that the arrow above the adjuster will point to the number indicated on the adjuster. The depth of nailing is the deepest when the arrow points to the number 1. It will become shallower as the arrow points to higher number. The depth can be changed in approx. 1.0 mm increments per graduation. If nails cannot be driven deep enough even when the arrow points to the number 1, increase the air pressure. If nails are driven too deep even when the arrow points to the number 9, decrease the air pressure. Generally speaking, the tool service life will be longer when the tool is used with lower air pressure and the adjuster set to a lower number.
