FUEL/REFUELING

Gasoline/oil mixture

-The engine of the pole hedge trimmer is a highly efficient two-stroke engine that runs on a mixture of gasoline and two-stroke engine oil. The engine is designed to use regular unleaded gasoline with a min. octane value of 91 ROZ. If such gasoline is not obtainable, instead use gasoline with the highest octane value available. This will not cause any damage to the engine, but may result in poor engine performance. Similar results are to be expected when leaded gasoline is used. To obtain optimal engine performance, and for the sake of human health and the environment, where possible use unleaded fuel.

-Two-stroke engine oil (quality grade: TSC-3) must be added to the gasoline in order to lubricate the engine. The engine has been designed to use environmentfriendly DOLMAR 2-stroke oil, which is to be mixed at a ratio of 50:1. This specially developed oil ensures prolonged engine service life and reliable engine performance with an absolute minimum of exhaust gas emissions. It is imperative to strictly observe the 50:1 mixture (Gasoline/DOLMAR 2-stroke oil), as reliable performance of the pole hedge trimmer cannot be guaranteed otherwise.

-Correct gasoline/oil mixture:

Mix 50 parts gasoline with 1 part DOLMAR 2-stroke engine oil (see also table on the right).

NOTE: When preparing the gasoline/oil mixture, first mix all of the amount of oil required with half the amount of gasoline required. Add the remaining gasoline and shake the mixture well before replenishing the tank.

Do not add more oil then prescribed. If too much oil is added this will produce additional combustion residue, thus polluting the environment and clogging the muffler and the cylinder exhaust channel. In addition, overall fuel consumption will also increase and poorer engine performance is to be expected.

Handling of petroleum products

Always handle fuel with the utmost care and attention. Since fuel contains substances similar to solvents, refueling must be done outdoors or in wellventilated areas. Do not inhale gasoline fumes and avoid any skin contact with gasoline or oil. Human skin will dry out if in contact with petroleum over an extended period of time. This may result in various skin diseases and allergic reactions.

Gasoline or oil coming into contact with the eyes can cause severe eye irritation. Should gasoline or oil come into contact with your eyes, immediately rinse your eyes with large amounts of clean water. Do not hesitate to see a doctor if irritation persists.

Refueling

The engine must be switched off.

-Thoroughly clean the area around the fuel filler cap (2), to prevent dirt from getting into the fuel tank (1).

-Unscrew the fuel filler cap (2) and fill the tank with fuel.

-Tightly screw on the fuel filler cap (2).

-Clean screw fuel filler cap (2) and tank after refueling.

Fuel storage

-Fuel deteriorates if stored over an extended period of time.

-Purchase only the amount of fuel to be used over a 4-week period.

-Use only approved petroleum-storage containers.

-The gearbox of the pole hedge trimmer should be greased every 20 working hours. Add approx. 10cc of lubricant (Shell Alvania No. 3 or equivalent) to the gearbox via the grease nipples. (Some grease will emerge from the head of the gearbox (located at the base of the blade) when the pole hedge trimmer is set in motion the first time after greasing. Use this as a rough indicator for the amount of grease to supply.)

Note: Observe greasing intervals and the amount of grease to be supplied. Mechanical parts of the pole hedge trimmer may be damaged if grease is not supplied at the prescribed intervals or if an insufficient amount of grease is added.

Fuel tank filter

-The inside of the fuel tank is equipped with a filter (1) that cleans the fuel before it enters the carburetor.

-Visually check the filter at regular intervals. To do so, use a piece of wire formed into a hook and draw the filter out of the tank (2). Replace the filter if it is hardened, clogged up, or excessively contaminated.

-Inadequate fuel supply as a result of a deteriorated fuel filter may result in poor engine performance. In order to ensure that the required amount of fuel enters the carburetor, replace the fuel filter whenever in doubt of its condition.

Cleaning the muffler outlet

-Check the condition of the muffler outlet (3) at regular intervals.

-Use a suitable tool to remove excessive carbon residue that accumulates around the muffler outlet. Take special care to prevent removed carbon residue from entering engine parts.

Cleaning the spark arrester

-The spark arrester should be cleaned every 50 working hours.

-Have the spark arrester cleaned at your dealership or by an authorized service agent.

For all maintenance work not mentioned in this instruction manual, please contact your dealership or an authorized service agent.

Daily inspection and maintenance

To ensure a long service life of your pole hedge trimmer, perform the following inspections and maintenance on a daily basis.

-Always check for loose or missing parts before starting operation. Pay special attention to the cutting unit and make sure that the cutter blade lock screws are well tightened.

-Check for clogging of the cooling air passages and the cooling fins of the cylinder before starting operation. Clean if necessary.

-Each day after using the pole hedge trimmer perform the following.

Clean the outside of the pole hedge trimmer; check for damage and loose parts.

Clean the air filter. Clean the filter several times a day if working in extremely dusty conditions.

Check the cutter blades for damage. Make sure that the blades are securely mounted.

STORAGE

If the pole hedge trimmer is to be stored for an extended period of time, proceed as follows:

-Drain all fuel from the tank and carburetor.

-Remove the spark plug and add a few drops of two-stroke oil through the spark plug hole. Gently pull out the starter rope to ensure that the oil is evenly distributed inside the engine. Replace and tighten the spark plug.

-Clean the entire pole hedge trimmer and apply a thin layer of oil to the metallic surfaces of the machine. Secure and protect the blades with the blade cover provided. Store the pole hedge trimmer in location that is free of humidity.
