FUEL
Petrol is very flammable. Do not use or fuel the multi-cutter near a flame, sparks or while smoking. Allow the engine to cool before re-fuelling. Fuel the engine at least 3m away from your work area.
Use a ratio of 25:1 unleaded petrol to mineral oil. Mix well in an appropriate mixing bottle. For semi-synthetic or synthetic oils check the oil manufacturer’s guidelines to determine the correct ratio.

• Unscrew the fuel cap, and fuel the machine to 80% capacity. Fas- ten the fuel cap tightly and wipe up any spillage.
• Ensure that any stored petrol/oil mixture (2-stroke) is clearly marked in a separate can and only stored for 4-6 weeks. If the multi-cutter is not going to be used for a long period, drain the mixture from the fuel tank, start the engine and drain the carburetor of any remaining fuel.
• Dispose of any unwanted 2-stroke mixture at an authorized recy- cling point.

Operating the Brushcutter:
Operate the throttle trigger with your right hand and hold the barrier handle with your left hand.

• Always keep a firm grip with both hands during operation.
• The brushcutter should be held at a comfortable position with the trigger handle about hip height. Adjust the harness to suit
• Maintain a firm footing in case the machine hits a solid object and kicks back.
• Do not use the brushcutter near fencing, posts, buildings or other immovable objects -use the line trimmer attachment.
• Best results are obtained if you cut from right to left in a broad sweeping action.
• If a hard object is hit. stop the machine and inspect for any damage straight away.
• Never attempt to sharpen the blade. It is reversible so should be turned over when blunt. The blade must remain balanced. Always check for any damage before use and replace a damaged blade immediately.

To avoid bums from the hot engine, never operate the unit with the bottom of the engine above waist level or on the operator’s left side. Always position the unit on the users right side.

ASSEMBLY, cont’d
Line Trimmer Attachment:

• Slide the shield onto the attachment shaft and fit over the bracket, as in Fig. 11.
• Fix the bolt through the holes in the tabs on the shield and the slots in the bracket on the attachment shaft.
• Secure, as shown in Fig. 11. using the flat washer. lock washer and nut.
• lighten securely and remove the protective packaging from the line cut-off blade.

Operating the Line Trimmer:

• Operate the throttle trigger with your right hand and hold the barrier handle with your left hand.
• Always keep a firm grip with both hands during operation.
• The line trimmer should be held at a comfortable position with the trigger handle about hip height. Adjust the harness to suit.
• Maintain a firm footing in case the machine hits a solid object and kicks back.
• Cut tall grass from the top down to prevent the grass from wrapping around the shaft housing and string head which may cause overheating and damage. If grass becomes entangled stop the engine completely and remove the grass.
• Always position the unit on the operator’s right side. Using it on the left side will expose the user to the exhaust and hot surfaces which can result in burns.

Adjusting the Throttle Cable:

• After releasing the throttle lever, pull the throttle cable.
• The normal play is 1 or 2 mm when measured at the carburetor side end.
• If the play is too short or long, take off the air cleaner cover, loosen the locknut (1) and adjust (2).

REPLACEMENT OF SPOOL AND LINE

To replace the line or spool:

• Stop the engine.
• Lay the trimmer on the floor so that the cutting head is facing up.
• Remove the bump knob/retaining cap by turning it anti-clockwise.
• Remove the empty spool being careful not to lose the spring behind the head.
• Clean the head thoroughly and inspect for any worn or damaged parts.

To reload the spool with line:-

• Cut two lengths of spare line 3 metres long.
• Position each line in the two holes located in the centre of the spool. as in Fig. 13, and wind in the direction of the arrow on the spool (see Fig. 12) keeping the line tight at all times, as in Fig. 14.
• Wind the line on until you have about 15cm left then secure the lines into the slots on the tabs, as shown in Fig. 15.
• Insert the lines on the spool into the eyelets on the trimmer head as in Fig. 16
• Place the spool on the drive shaft.
• Release the lines from the tabs by sharply pulling each line while pushing down on the spool.
• Push down on the spool to reveal the drive shaft then place the bump knob/retaining cap onto the drive shaft as in Fig. 17.
• Secure the knob/retaining cap by turning it clockwise.

If you need to replace the whole spool, follow the instructions above, omitting the references to refilling the line.

REPLACEMENT OF PRUNER CHAIN

• Remove the sprocket wheel cover.
• Remove the guide bar and chain.
• Remove the old chain and replace with the new chain.
• Mount the guide bar and then fit the saw chain around the bar and sprocket, paying particular attention to the correct direction of the chain.
• Fit the chain tensioner into the lower hole of the guide bar.
• Attach the sprocket wheel cover and loosely tighten the nut.
• Using the black T-shaped spanner turn the chain tensioner clockwise until the chain fits snugly onto the guide bar.
• lighten the sprocket wheel cover nut, then using gloves, pull the chain around the guide bar to check that the chain has the correct tension without any tight spots.
• Fill the chain oil reservoir with chain oil and before cutting, run the chain at medium speed to make sure chain oil is thrown off. This ensures that the chain is being lubricated. Be sure to wipe excess oil off after filling. You may also want to drain the oil tank after each use to prevent spillage. Oil from the tank can be stored and used, it does not have to be disposed of.

Note: After every second chain is worn out, the drive sprocket should be replaced. To change the drive sprocket, remove the spring ring from the driveshaft and pull the drive sprocket and the two washers off the drive shaft. If necessary use a penetrating lubricant. Then slide the replacement parts onto the driveshaft and secure them with the spring ring.
It is very important to maintain proper chain tension as Incorrect chain tension can cause the guide bar to wear and the chain to come off. You should be able to pull the chain 5-6mm off the bar. If the chain needs to be sharpened a 5/32″ chain file should be used, these can be purchased from Handy Garden Machinery under the product code: HP-106.

Operating the Pruner:

• The Pruner is equipped with a low kickback chain, however, sometimes kickback can occur so always hold the unit firmly in both hands.

• Thin branches can be cut off with a single cut but if the branch is long it is preferable to cut it off in several pieces.

• For larger branches follow the diagrams below for a safe clean cut Make the first cut from underneath and cut through one-third to half of the branch.
  

• Do not work at an angle higher than 60 degrees as there is a danger of being injured by branches falling without warning. Also be careful not to trip over fallen branches.
  Before every use, check the level of the chain oil in the reservoir. After each use clean any oil or sawdust out of the area under the plastic cover with a brush or compressed air. Be especially sure to clean out the oil duct.

OPERATION

Starting the Multicutter:

•  Place the machine on the floor, as this may make it easier to start.

• Move the ignition switch to the on or I position (see Fig. 0).

• Move the choke lever upwards to the “start’ position (for cold start only) (Fig. P).

• Push the primer bulb 10 times until the petrol/oil mixture fills the primer bulb (Fig. 0).

• Squeeze the safety lever, then the throttle; push in the throttle lock button with your thumb (see Fig. S).

• Pull the recoil starter 2-3 times until the engine fires (Fig. R).

• Push the choke lever down to the ‘run” position and pull the starter again until the engine starts. Squeeze the throttle to release the throttle lock.
  Warning: failure to push the choke to the “run” position after the engine has fired will flood the engine.

• Allow the engine to run idle for about 10 seconds to warm it up.
  Note: if restarting a warm engine there is no need to move the choke lever or prime the primer bulb.
  

Stopping the Multicutter:

• Release the throttle trigger and allow the engine to idle for a few moments.
• Move the ignition switch to the “off” position (Fig. T).

Note: The attachments may continue to rotate for a few seconds after the engine has stopped.
During the first 10 hours of work run the engine at a moderate speed. Ensure that all nuts. bolts and screws are securely tightened before every use of the Multicutter.
Always position the unit on the operator’s right side. Using it on the left side will expose the user to the exhaust and hot surfaces which can result in burns.

MAINTENANCE

The engine of the multi-cutter must be at a complete stop during assembling, cleaning and any maintenance that may be necessary.
Air Filter:
Accumulated dust in the air filter will reduce engine efficiency, increase fuel consumption and allow abrasive particles to pass into the engine. Remove and clean the air filter regularly to ensure optimum performance.

• Remove the air filter cover by releasing the securing screws and lifting it off.
• Tap the filter to remove light surface dust.
• Heavy deposits should be washed out in soapy water. Allow the filter to dry completely.

Fuel Filter:
Check the fuel filter periodically but be careful not to allow dust to enter the fuel tank.

• The fuel tank is fitted with a filter which is situated at the free end of the fuel pipe and can be extracted by using a piece of hooked wire.
• If the filter is dirty replace it straight away.
• If the inside of the fuel tank is dirty rinse out with petrol.

Spark Plug:
Check the spark plug after every 10-15 hours of use.

• Remove the spark plug cover.
• Using the plug spanner supplied. remove the spark plug by turning it anti-clockwise.
• Clean and adjust the gap to 0.6-0.7mm.
• Replace any damaged or visibly worn spark plug.
• Install the new/cleaned spark plug to finger tightness and tighten fully with the spanner.

Servicing:

• We recommend that your petrol multi cutter is serviced after 15 hours of use and thereafter every 2 years.
  When you finish working, clean the multi-cutter completely, removing any dirt and making sure there is no grass wrapped around the cutting tools. Replace the blade covers on the hedge trimmer and pruner. Be careful not to hit or damage the fuel tank when you put the machine on the ground. Store away from direct sunlight and preferably hang the multi-cutter off the floor by the top handgrip. If storing for a long period, drain completely of fuel. Remove the spark plug. put a few drops of 2-stroke oil into the cylinder and pull the recoil starter a few times to distribute the oil. Replace the spark plug. This protects all metal engine parts against rust.
  You must periodically check that all screws are securely tightened. Failure to regularly check the machine may affect performance and operator safety.
