Do not place the contact element against the workpiecewith excessive force.B. Pull the trigger fully and hold it on for 1-2 seconds afternailing.• For No. 1 method, set the change lever to theposition.For No. 2 method, set the change lever to theposition. After using the change lever to change thenailing method, always make sure that the changelever is properly set to the position for the desirednailing method.

(Fig. 22)With tool disconnected, make daily inspection to assurefree movement of the contact element and trigger. Do notuse tool if the contact element or trigger sticks or binds.(Fig. 23)Make sure that the trigger is locked when the changelever is set to the position. (Fig. 24)When the tool is not to be used for an extended period oftime, lubricate the tool using pneumatic tool oil and storethe tool in a safe place. Avoid exposure to a direct sunlightand/or humid or hot environment. (Fig. 25 & 26)Maintenance of the compressor, air setand air hose (Fig. 27 & 28)After operation, always drain the compressor tank and theair filter. If moisture is allowed to enter the tool, It mayresult in poor performance and possible tool failure.Check regularly to see if there is sufficient pneumatic oil inthe oiler of the air set. Failure to maintain sufficientlubrication will cause O-rings to wear quickly. (Fig. 29)Keep the air hose away from heat (over 60°C, over140°F), away from chemicals (thinner, strong acids oralkalis). Also, route the hose away from obstacles which itmay become dangerously caught on during operation.Hoses must also be directed away from sharp edges andareas which may lead to damage or abrasion to the hose.(Fig. 30)To maintain product SAFETY and RELIABILITY, repairs,any other maintenance and adjustment should beperformed by Makita Authorized Service Centers, alwaysusing Makita replacement parts.OPTIONAL ACCESSORIESCAUTION:• These accessories or attachments are recommendedfor use with your Makita tool specified in this manual.The use of any other accessories or attachments mightpresent a risk of injury to persons.
