Fuel Mixture
The fuel: oil ratio is 50 parts gasoline to 1 part oil or 50:1.
6. When refilling the Pruner fuel tank, clean around the fuel tank cap to prevent dirt and debris from entering the tank during cap removal.
7. Always shake the premix fuel container momen­tarily before filling the fuel tank.
50:1
Note: Never use a mixing ratio less than
50:1 regardless of the oil package mixing instructions. Ratios less than 50:1, (for example, 60:1, 80:1, 100:1), reduce the amount of lubrication to the internal moving parts of the engine and can cause damage.

8. Always use a spout or funnel when fueling to reduce fuel spillage.
9. Fill the tank only to within 1/4-1/2 in. (6 mm-13 mm) from the top of the tank. Avoid filling to the top of the tank filler neck.

5. Close the container tightly and shake it momen­tarily to evenly mix the oil and the gasoline before filling the fuel tank.
This XQLW is equipped with a fuel primer and a choke system. To start a “cold” engine properly, perform the following procedure:
1. Pump the primer bulb at the bottom of the carbu­retor until fuel can be seen flowing through the fuel return line to the fuel tank.
(Flowing fuel should be almost clear, not foamy
or full of bubbles.)

Maintenance
Maintenance, replacement or repair of emission control devices and systems may be performed by any repair establishment or individual; however, warranty repairs must be performed by a dealer or service center authorized by MARUYAMA Manufacturing Company, Inc. The use of parts that are not equivalent in performance and durability to authorized parts may impair the effectiveness of the emission control system and may have a bearing on the outcome of a warranty claim.
Maintenance on today’s low-emission engines is even more critical for longest life and best perfor­mance. particularly critical are air and fuel filters, spark plug heat range, cooling air intake area and proper gaps of coil and plug.
Idle Speed Adjustment
The cutting head may be rotating during idle speed adjustment. Wear the recommended personal protec­tive equipment and observe all safety instructions. Keep hands and body away from the cutting head.
When the throttle trigger is released, the engine should return to an idle speed between 2700 and 3300 RPM, or just below the clutch engagement speed. The cutting head must not rotate and the engine should not stall (stop running) at engine idle speed.
To adjust the engine idle speed, rotate the idle speed adjustment screw on the carburetor.
This HQJLQH is equipped with Dnon-adjustable fuel
PL[ture carburetor. The engine idle speed is the RQO\adjustment for the operator.
WARNING
• Idle speed adjustment should be checked each time the unit is operated.
WARNING
POTENTIAL HAZARD
• Engine must be running to make carbu­retor adjustments.
When engine is running, saw chain is
• moving and other parts are moving.
WHAT CAN HAPPEN
• Contact with moving saw chain or other moving parts could cause serious per sonal injur y or death.
HOW TO A
• Keep hands, feet and clothing away from saw chain and other moving parts.
• Keep all bystanders and pets away from unit while making carburetor adjust-
ments.
VOID THE HAZARD
-
Idle Speed Adjustment Screw
• Turn the idle speed screw in (clockwise) to increase the engine idle speed.
• Turn the screw out (counterclockwise) to decrease the engine idle speed.
If idle speed adjustment is necessary, and after adjustment the cutting head rotates or the engine stalls, stop using the Pruner immediately!
Contact your local authorized MARUYAMA Dealer for assistance and servicing.
Air Filter
Maintenance Interval
• The air filter should be cleaned daily, or more often when working in extremely dusty conditions.
• Replace after every 100 hours of operation.

Air Filter Cleaning
2. Remove the fuel cap.
1. Loosen the knob and remove the air filter cover.
2. Remove the foam element and filter screen from the air filter body.
3. Clean the foam element and filter screen with warm, soapy water. Let the screen and element dr y completely.
4. Apply a light coat of SAE 30 motor oil to the foam element and squeeze out all excess oil.
5. Reassemble the filter screen and foam element to the air filter body.
Air Filter Cover
Filter Screen
3. Using a wire hook, gently pull the fuel filter out through the fuel filler opening.
Use caution not to “fishook” the fuel tube.
Replace immediately if punctured!
Fuel Pick-up Hose
Wire
Fuel Filter
4. Grasp the fuel hose next to the fuel filter fitting and remove the filter, but do not release the hose.
5. While still holding on to the fuel hose, attach the new fuel filter.
Foam Element
6. Reinstall the air filter cover and tighten the knob.
Fuel Filter
Maintenance Interval
The fuel filter should be replaced after every 100 hours of operation. Fuel filters needing more frequent replacement may indicate debris in fuel tank.
Fuel Filter Replacement
The fuel filter is attached to the end of the fuel pick-up hose inside the fuel tank.
To replace the fuel filter:
6. Drop the new fuel filter back into the fuel tank.
7. Make sure that the fuel filter is not stuck in a cor­ner of the tank, and that the fuel hose is not dou­bled over (kinked) before refueling.
Spark Plug
Maintenance Interval
• The spark plug should be removed from the engine and checked after each 25 hours of operation.
• Replace the spark plug after every 100 hours of operation.
Spark Plug Maintenance
1. Twist the high tension lead boot on the spark plug back and forth a couple of times to loosen the boot, then pull the boot off of the spark plug.
1. Make sure the fuel tank is empty.
2. Remove the spark plug.

3. Clean the electrodes with a stiff brush.
Cylinder Cooling Fins
.024” - .028” (0.6 - 0.7 mm)
4. Adjust the electrode air gap to .024-.028 in. (0.6-
0.7 mm).
5. Replace the spark plug if it is oil-fouled, damaged, or if the electrodes are worn down.
6. Do not overtighten the spark plug when installing. The tightening torque is 95-148 in.-lbs. (10.7-16.6 N·m).
7. Always use only the specific heat range of spark plug. This is particularly critical with today's low­emission engines. For best results, use the exact replacement.
Maintenance Interval
• The cylinder cooling fins should be cleaned after every 25 hours of operation, or once a week, whichever comes first.
• Air must flow freely around and through the cylin­der cooling fins to prevent engine overheating. Leaves, grass, dirt and debris buildup on the fins will increase the operating temperature of the engine, which can reduce engine performance and shorten engine life.
Cooling Fin Cleaning
1. With the engine at ambient (room) temperature, loosen the knob and remove the air filter cover.

WARNING
POTENTIAL HAZARD
• When engine is running, saw chain is moving and other parts are moving.
WHAT CAN HAPPEN
• Contact with moving saw chain or other moving parts could cause serious per sonal injury or death.
-
HOW TO AV
•
Always turn off your pruner before you clean or perform any maintenance on it.
The MARUYAMA XQLW will provide maximum per­formance for many, many hours if it is maintained properly.
Good maintenance includes regular checking of all fas­teners for correct tightness and cleaning the entire machine.
OID THE HAZARD
Storage
For long term storage of the Pruner:
1. Empty the fuel tank into a suitable fuel storage container.
2. Pump the primer bulb on the carburetor until all fuel is discharged through the clear fuel return hose.
CAUTION
POTENTIAL HAZARD
• Oil may squirt out of the spark plug opening when you pull the starter grip.
WHAT CAN HAPPEN
• Oil can cause eye injuries.
HOW TO AVOID THE HAZARD
• Protect your eyes and keep your face away from the spark plug opening.
6. Pull the starter grip once.
7. Slowly pull the starter grip to bring the piston to the top of the cylinder (TDC).
8. Reinstall the spark plug.
9. Store the XQLW in a dry place away from exces­sive heat, sparks or open flame.
3. Run the engine to remove any fuel that may remain in the carburetor.
4. Perform all regular maintenance procedures and any needed repairs.
5. Remove the spark plug and squirt a very small amount of oil into the cylinder.
