Oil Pump Adjustment

Guide bar and saw chain lubrication is 

automatically provided by an adjustable-

rate oil pump designed to operate 

whenever the clutch drum rotates. A 

temporary increase in oil flow rate is 

often desirable when cutting hardwoods 

or large-diameter softwoods, and can be 

provided as follows:
1.  Stop the engine and verify that the 

engine stop switch is in the “OFF” 

position. 

Oil Requirements

  When available, use Shindaiwa 

Premium bar and chain oil. 

  When Shindaiwa oil is not available, 

use a premium 30-weight oil specifically 

blended for bar and chain lubrication. 

  For cold weather operation, bar oil 

may be thinned by mixing with clean 

kerosene at a ratio of 1:1. 

Filling the Oil Reservoir

  Place the saw on its side (clutch cover 

down), and wipe any chips or debris 

from around the oil cap.

  Remove the oil cap at the front of the 

saw. 

  Fill the oil reservoir with bar and chain 

oil and replace the cap. 

  Wipe spilled oil from handles and 

controls before starting the saw. 

Bar Oil / Filling with Oil

CAUTION!

Proper lubrication is critical to the 

performance and service life of your 

saw’s oil pump, guide bar, and saw 

chain! Always use a high quality 

lubricating oil designed for saw 

chain lubrication! Never use dirty or 

reclaimed oil!

WARNING!

Minimize the risk of fire, 

burns, and personal injury!

IMPORTANT!

Shindaiwa high-performance 2-cycle 

engines are designed to operate on a 

50:1 mixture of unleaded gasoline and 2-

cycle mixing oil. Using a fuel mixture less 

than 50:1 ratio (such as 80:1 or 100:1) 

can cause catastrophic engine failure! 

 

STOP

 engine before refueling.

 

ALWAYS

 allow the engine to cool 

before refueling!

 

ALWAYS

 open the fuel cap slowly 

to allow any pressure build-up in the 

tank to release fuel vapor slowly.

  Avoid overfilling and wipe up all 

spilled fuel. Move the engine at 

least 3 meters from the fueling 

point, storage area and other 

readily flammable materials before 

restarting!

 

ALWAYS

 inspect the unit for fuel 

leaks before each use. During each 

refill, make sure there are no fuel 

leaks around the fuel cap and/or 

tank. If a fuel leak is evident, stop 

using the unit immediately. Fuel 

leaks must be repaired before using 

the unit.

 

NEVER

 smoke or light any fires 

near the engine or fuel source!

 

NEVER

 place any flammable 

material near the engine muffler!

 

NEVER

 operate the engine 

without the muffler in good working 

condition.

CAUTION!

  Some types of gasoline contain 

alcohol. Never use any type of 

gasoline containing more than 

10% alcohol by volume! More than 

10% alcohol by volume may affect 

the lubricating qualities of 2-cycle 

mixing oils reducing engine life 

and/or causing engine failure. 

  Generic mixing oil and marine 

engine oil may not be intended for 

use in high-performance 2-cycle 

engines and should never be used 

in Shindaiwa engines. Mixing 

oils not intended for use in high-

performance air-cooled 2-cycle 

engines can cause excessive 

carbon deposits, reduce engine life 

and/or cause engine failure. 

1.  Use only fresh, clean unleaded gasoline 

with a pump octane rating of 87 or 

higher. 

2.  Mix fuel with a 2-cycle mixing oil 

designed for use in high-performance 

2-cycle air-cooled engines. 

3.  Place the saw on a hard surface with the 

fuel cap up and wipe any chips or debris 

from around the fuel cap. 

4.  Remove the fuel cap and fill the tank 

with clean, fresh 2-cycle fuel mix. Avoid 

overfilling and fuel spillage. 

5.  Wipe any spilled fuel and move the saw 

at least 3 meters from the fueling point 

before starting the engine.

2.  Place the saw on its side, with the clutch 

cover facing up. 

3.  Use a screwdriver to push down and 

turn the oil flow rate adjustment screw. 

  Clockwise to decrease bar and chain 

lubrication. 

  Counter-clockwise to increase bar and 

chain lubrication.
