Start-up instructions
Please refer to the quick use manual.

Warning: Please use this machine correctly. Please push the branches into the inlet hopper and the automatic biting system will cut them into pieces.

If the feed is too thick or much, please mind the status of the machine and the engine when slicing. Make sure the rotating speed of the gasoline engine all the time. In order to ensure the working efficiency and experience, please feed materials properly. When chipping dry branches, please note that the maximum diameter should not exceed 4cm. If the branches are too thick, please chop or trim it and then shred it separately. When chopping the branches approaching the limit diameter, please grasp the material and push with your hands to avoid the danger of swinging back and forth. The emergency stop switch is only used for emergency situations, normal shutdown should firstly reduce the engine to idle speed for a few minutes, then switch off the engine.

Maintenance

Tip: Regular inspection and maintenance work can effectively ensure the normal operation of the machine.

Warning: Please stop the machine before doing any maintenance, inspection and so on, and wait until it stops rotating completely. Place the machine in a horizontal position.

Maintenance of gasoline engine

• Routine inspection and maintenance can ensure the perfect performance of the machine. Seasonal maintenance is strongly recommended by professionals.
• The adjustment of carburetor is required to be operated by the specialized person of distributor. The incorrect regulation of carburetor will directly affect the performance of gasoline engine.
• Clean the gasoline engine regularly, especially the location of the oil injection, gasoline tank. Regularly check if the oil is in normal level.
• After the oil is wiped up, put the oil ruler back and check the oil level. (see right picture), if it’s below the minimum level, refill the oil, if the oil is above the highest position, please release some oil appropriately.
• When you clean the machine with a high pressure water jet , please do not pour water into the bearings and inside of the gasoline engine, otherwise, these parts will be damaged.

How to change the oil

• Please put the prepared oil container to the bottom of the oil outlet.
• Screw off the oil seal bolt and drain the oil. (see the right picture)
• Quickly place the oil guide pipe to collect the oil avoid oil overflow.

Maintenance of air filter
Timely cleaning and maintenance of air filter can effectively prolong the service life of gasoline engines. Please replace the damaged air filters in time. Remove the air filter cover, take out the filter element, wash the filter element in soapy water, and rinse it clean. After drying, add two drops of oil to increase the air filtration effect, and install it back in proper order.
Warning: Prohibit starting a gasoline engine without air filter!

Inspection of ignition system
Check the spark plug regularly. Spark plug’s contact spacing is 0.6mm-0.7mm, clean up the carbon deposition between contacts In time.

Cleaning of cylinder cooling sink
The cylinder cooling sink is the main way of cooling down the gasoline engine in operation. Timely cleaning can effectively prevent the cylinder from being damaged due to overheating.

Belt maintenance

Please check the tightness of the belt regularly and adjust the tightness of the belt in time. (see the right picture)

• Loosen the fixed bolts(1)
