5. 6. 7. Service 1. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. 2. Follow instruction for lubricating and changing accessories. 3. Keep handles dry, clean and free from oil and grease. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. Dress properly. Do not wear loose clothing or jewellery.
12. 13. Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for cutting plastic, masonry or non-wood building materials. Use of the chain saw for operations different than intended could result in a hazardous situation. Causes and operator prevention of kickback: Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.
Use of non-genuine Makita batteries, or batteries that have been altered, may result in the battery bursting causing fires, personal injury and damage. It will also void the Makita warranty for the Makita tool and charger. 3. 4. Tips for maintaining maximum battery life Charge the battery cartridge before completely discharged. Always stop tool operation and charge the battery cartridge when you notice less tool power. 1. Never recharge a fully charged battery cartridge.
Tool / battery protection system FUNCTIONAL DESCRIPTION The tool is equipped with a tool/battery protection system. This system automatically cuts off power to the motor to extend tool and battery life. The tool will automatically stop during operation if the tool or battery is placed under one of the following conditions. CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool.
Capacity indicator status On Off NOTE: Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.

OPERATION WORKING WITH THE CHAIN SAW Lubrication CAUTION: The first time user should, as a minimum practice, do cutting logs on a saw-horse or cradle. Saw chain is automatically lubricated when the tool is in operation. Check the amount of remaining oil in the oil tank periodically. To refill the tank, lay the chain saw on its side and remove the oil tank cap. The proper amount of oil is 200 ml. After refilling the tank, make sure that the oil tank cap is tightened securely.
Bucking A 1. Rest the bottom edge of the chain saw body on the wood to be cut. B B A Limbing CAUTION: Limbing may only be performed by trained persons. A hazard is presented by the risk of kickback. 2. With the saw chain running, saw into the wood while using the rear handle to raise the saw and the front one to guide it. Use the spike bumper as a pivot. 3. Continue the cut by applying slight pressure to the front handle, easing the saw back slightly.
When felling trees, follow the proceduers below: 45 o 1. Cut a scarf as close to the ground as possible. First make the horizontal cut to a depth of 1/5 -1/3 of the trunk diameter. Do not make the scarf too large. Then make the diagonal cut. 2 1/2 45 o 1 ► 1.

— — Sharpen the shortest cutter first. Then the length of this shortest cutter becomes the standard for all other cutters on the saw chain. Guide the file as shown in the figure. Cleaning the guide bar Chips and sawdust will build up in the guide bar groove. They may clog the bar groove and impair the oil flow. Clean out the chips and sawdust every time when you sharpen or replace the saw chain. 1 2 ► 1. File 2.
