VIII Technical maintenance
8.1 Air Filter
Check the air filter regularly. Air filter cartridge dust jams will reduce engine power and shorten
the service life of the cylinder. If the filter cartridge is dirty, you must use warm water and detergent,
clean with a dry cloth to wipe dry after installation. If there is any breakage, the filter must be replaced.
Especially in dusty work environment, maintenance cycle is shorten appropriately.
8.2 Fuel filter
If the fuel filter blockage, machine speed decline, impact can be reduced. Methods: (1) open the lid,
with a metal hook the hook out of the tank and clean fuel filter (2) when clean fuel filter, and clean fuel
tank.
8.3 Carburetor
The fuel tank and carburetor often have residual oil. Over time, the residual oil into the oil. Residual oil
can jam the oil , the engine won't start. Therefore, when the machine idle for more than a week, you
must put the fuel vent. Methods: pull into the carburetor fuel oil foam rubber tubing to repeat
compressions bubble discharge of oil, fuel oil in the oil bubble and return pipe put dry after plugged
into the tubing.
8.4 Spark plug
To ensure the normal operation of the engine, reasonable spark plug gap is 0.5 -0.7 mm. Use steel
wire brush to clean carbon deposit. See image 5.
Image 5
8.5 Muffler
Regular cleansing dirt or use detergent to clean the silencer muffler import and export in the dirt.
8.6 Cylinder and gear lubrication
Cylinder lubrication: unscrew grease cover counterclockwise (see figure 2), join special cylinder
hammer picks 30 grams of fat, then grease cover clockwise to tighten.
Gear lubrication: with Allen wrench unscrew gearbox cover screws (see figure 1), in the adjacent gear
parts add 2 lithium grease 50 grams, then install the gearbox cover in place.
8.7Cylinder cooling fin
Remove dust regularly, to ensure that the cylinder heat dissipation is good. The driver for the air
cooling type. Cylinder radiator dust will directly affect the heat dissipation effect.

IX Failure analysis and troubleshooting methods
Problems analysis and solving
Example1: difficulties in starting engine in cooling state.
Whether the spark plug is moisture. →Dry the igniter plug
↓
Whether the spark plug produces electric spark →replace the igniter plug
↓
Too much fuel absorbed →lessen the fuel supply
Example 2: Difficulties in restarting after a sudden stop
Whether fuel runs out or the Carburetor is blocked →Refill fuel tank or clean the
carburetor
↓
Whether the fuel filter is blocked →clean the fuel filter
↓
Too much carbon deposit in igniter plug →Remove carbon deposit
Example 3: Reluctance in speeding and weakness in power
Carbon deposit cover the entrance of the cylinder or
silencer
→Remove carbon deposit
↓
Whether the oil tube and the air vent on the fuel Tank
cover is blocked
→Clean
↓
Blockage in air filter →Clean the filter
Example 4: abnormal sound
Carbon deposit found in combustion chamber →Remove carbon deposit
↓
Serious abrasion in active components →Replace
Example 5: The machine is working normally, but the efficiency of cracking is very low
The head of the chisel is attrited badly →replaced or renew
Please contact with Sales Agency of the Crusher if your machine needs further mending.
