FUELS/REFUELLING

Fuel and oil mixture

Inspect the fuel tank and ll with clean, fresh fuel of the proper mixture to assure the longer life of the tool. Use the following mixed gas.

Gasoline : Makita genuine two-stroke engine oil = 50 : 1 or Gasoline : Other manufacturer’s two-stroke engine oil = 25 : 1 recommended

FOR CALIFORNIA REGULATION : THIS EQUIPMENT IS CERTIFIED TO OPERATE ON GASOLINE + TWO-STROKE ENGINE OIL

WHEN MIXING GASOLINE WITH TWO-STROKE ENGINE OIL, USE ONLY GASOLINE WHICH CONTAINS NO ETHANOL OR METHANOL

(TYPES OF ALCOHOL). THIS WILL HELP TO AVOID POSSIBLE DAMAGE TO ENGINE FUEL LINES AND OTHER ENGINE PARTS. DO NOT MIX GASOLINE AND OIL DIRECTLY IN THE FUEL TANK.

IMPORTANT:

Failure to follow proper fuel mix instructions may cause damage to the engine.

The engine of the Hedge Trimmer is a high-efciency two-stroke engine. – It is run with a mixture of fuel and two-stroke engine oil. The engine is designed for unleaded regular fuel with a min. -octane value of 91 ROZ. In case no such fuel is available, you can use fuel with a higher octane value. This will not damage the engine, but may cause poor operating behavior. A similar situation will arise from the use of leaded fuel.

To obtain optimum engine operation and to protect your health and the environment, only unleaded fuel should be used!

For lubricating the engine use a two-stroke engine oil (quality grade:TC-3), – which is added to the fuel. The engine has been designed for use with MAKITA two-stroke engine oil and a mixture ratio of 50:1 only to protect the environment. In addition, a long service life and a reliable operation with a minimum emission of exhaust gases is guaranteed. It is absolutely essential to observe a mixture ratio of 50:1 (MAKITA 2-stroke engine oil), otherwise the reliable function of the

Hedge Trimmer cannot be guaranteed.

The correct mixture ratio: – Mix 50 parts gasoline with 1 part MAKITA 2-stroke engine oil (See table on

the right).

Observe the Safety Instructions on page 4

NOTE: For preparing the fuel-oil mixture, rst mix the entire oil quantity with half

o the fuel required. In an approved can which meets of exceeds all local

code standards, then add the remaining fuel.

Thoroughly shake the mixture before lling it into the Hedge Trimmer’s

tank.

It is not wise to add more engine oil than specied to ensure safe operation. It will only result in a higher production of combustion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the mufer. In addition, the fuel consumption will rise and the performance will decrease.

Handling petroleum products

Utmost care is required when handling fuel. Fuel may contain substances similar to solvents. Refuel either in a well ventilated area or outdoors. Do not inhale fuel vapors, avoid any contact of fuel or oil with your skin. Mineral oil, fuel, etc., product degrease your skin. If skin comes in contact with these substances repeatedly or for an extended period of time, various skin diseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil, fuel etc. If oil, fuel, etc., comes into your eyes, immediately wash them with clear water.

If your eyes are still irritated, see a doctor immediately!

OPERATION OF THE MACHINE

Be sure to carefully read and follow safety instructions. – Keep hands away from blades. Never grasp the exposed cutting blade or –

cutting edges, when picking up or holding the tool. Never touch the cutting device when starting the engine and during operation. –

Operate the Hedge Trimmer in such a manner as to avoid inhalation of –

the exhaust gases. Never run the engine in enclosed rooms (Risk of gas poisoning). Carbon monoxide is an odorless gas.

All protective installations and guards supplied with the machine must be –

used during operation. Never operate the engine with a faulty exhaust mufer or if it is missing. – Use the Hedge Trimmer only in good light and visibility. –

Always ensure a safe footing.

Never stand on a ladder and run the Hedge Trimmer. Keep both feet on the – ground.

Never climb up the trees with the Hedge Trimmer to perform cutting – operation.

Never work on unstable surfaces. – Remove sand, stone, nails, wire, etc. found within the working area. Foreign –

objects may damage the cutting blades. Before commencing cutting, the cutting blades must have reached full –

working speed. Always hold the Hedge Trimmer rmly with both hands on the handles only. –

The right hand grips the front handle of model HTR7610. –

This is the way to safely operate the machine. Use a rm grip with thumbs and ngers encircling the handles. – When you release the throttle, it takes a few moments before the cutting –

blades stop.

The Hedge Trimmer must not be used for cutting with fast idle. – The cutting speed cannot be adjusted with the throttle control in fast idle

position. When cutting a hedge, the machine should be held so that the blades form a –

15-30° angle with the cutting line. If the Hedge Trimmer is used with circular movements against the edge of the –

hedge, the twigs will be thrown directly to the ground. At vertical cutting, the Hedge Trimmer is used with circular pendulation, –

swinging up and down close to the hedge. Pay special attention when cutting hedges which are laid out a long a wire- –

fence and have grown through the fence. The blade must not contact the fence, otherwise the blades may be

destroyed. Do not use the Hedge Trimmer continuously for a long time. It is normal to –

take a break of 10 to 20 minutes after every 50 minutes operation. Should the cutting blades hit stones or other hard objects, immediately switch –

off the engine and inspect the cutting blades for damage. Replace damaged

blades before re-commencing work. The engine must be switched off immediately in case of any engine problems. – Operate the Hedge Trimmer with as little noise and contamination as –

possible. In particular check the correct setting of the carburetor and the fuel/ oil ratio.

Do Not attempt to remove jammed cut material when blades are running. Put – unit down, turn it off, and remove necessary cuttings.

MAINTENANCE INSTRUCTIONS

Turn off the engine and remove the spark plug connector when replacing or sharpening cutting tools, also when cleaning the cutter or cutting – device or carrying out any maintenance.

Never straighten or weld a damaged cutting blade. – Inspect the cutting blades with the engine switched off at short, regular intervals for damage. –

(Detection of hairline cracks by means of tapping-noise test.) Beware the teeth are sharp. Clean the Hedge Trimmer at regular intervals and check that all screw and nuts are well tightened. – Never service or store the Hedge Trimmer in the vicinity of naked ames to avoid res. – Always wear leather gloves when handling or sharpening the blades as they are sharp. –

Blade sharpening

If the edges are rounded and do not cut well any more, grind

off only the shaded portions. Do not grind the contact surfaces (sliding surfaces) of the top and bottom edges.

Before grinding, be sure to secure the blade rmly and – switch off the engine and remove the spark plug cap.

Wear gloves, protective glasses, etc. – An edge ground too much at a time or ground many times –

will lose its hardened layer. It becomes rounded and dull

very quickly in use.

Blade adjustment

The blades will wear with long use. When you nd that trimming is not as good as when the blades were new, adjust them as follows

1. Turn nut 1 loose.

2. Screw 2 in with the driver lightly till it stops turning, and then screw it back one quarter to a half turn.

3. Turn nut 1 tight, holding screw 2 at the same time with a driver.

4. Lubricate the blades after adjustments above with light oil.

5. Start the engine and operate the engine throttle on and off for a minute.

6. Stop the engine and touch the blades with your hand. If they are warm enough for you to keep your hand on, then you have made the proper adjustment. If they are too hot for you to keep touching, give screw 2 a little more turn back and repeat 5 to see if they are properly

adjusted.
