INTRODUCTION
This unit is designed for occasional homeowner use and
should not be used for commercial purposes or subjected
to heavy continuous use.
Your new chain saw can by used for a variety of projects
such as cutting firewood, making fence posts, felling small
trees, limbing, pruning at ground level, and light carpentry.
Cut only wood or wood products with your saw.
TOOLS FOR ASSEMBLY
Your User’s Kit may contain a combination wrench/screw-
driver (wrench) and is the only tool you will need to
assemble your unit and to adjust the saw chain tension.
ASSEMBLY REQUIREMENTS
Your new chain saw may require installation of the guide
bar, saw chain, sprocket cover, adjustment of chain, and
filling the oil tank with lubricating oil, before the unit is
ready for operation. Do not start the saw motor until the
unit is properly assembled. Read all instructions carefully.
Do not install any other size bar and chain than what is
recommended for your model.

GUIDE BAR/SAW CHAIN INSTALLATION
To Install Guide Bar
1.
Place power unit on flat surface and remove bar bolt
nuts and sprocket cover.
2.
Using a straight screwdriver or the scrench, if provid-
ed in your User’s Kit, turn the chain adjustment screw
(A) counterclockwise as far left as it will go, or until
the Tang (B) (projecting prong) is to the end of its
travel. (See Fig. 3A)
3.
Place the slotted end of the guide bar over the bar
bolts so the Tang (B) fits into the lower hole C) in the
guide bar (D). (See Fig. 3B)
To Install Saw Chain
1.
Spread the chain out with
the cutting edges (E) of the
chain pointing in the DIREC-
TION OF ROTATION. (See
Fig. 3C)
2.
Place the chain over the
sprocket (F) with drive links
fitting between sprocket
teeth. Guide the chain links
into the groove (G) on the top side of the guide bar
and around the nose. The saw chain will droop slight-
ly on the lower part of the guide bar. (See Fig. 3D)
3.
Install the sprocket cover (H). Place the cover over
the 2 bar bolts. Thread the retaining nuts (J) FINGER
TIGHT ONLY. (See Fig. 3E)
•
SAW CHAIN TENSION ADJUSTMENT
Proper tension of the saw chain is extremely important
and must be checked before starting, as well as during,
any cutting operation. Taking the time to make needed
adjustments to the saw chain will result in improved cut-
ting performance and prolonged chain life.
NOTE: A new chain and bar will need readjustment after
as few as 5 cuts. This is normal during the break-in peri-
od, and the interval between future adjustments will
lengthen quickly (Fig. 4).
To Adjust Saw Chain Tension:
1.
Loosen the bar retaining nuts (J) so they are hand
tight. (See Fig. 3A)
2.
Holding the nose of the bar up, use the screwdriver or
wrench if provided in your User’s Kit to turn the guide
bar adjustment screw (F) (Fig. 3B) clockwise to tight-
en the chain. Turning the screw COUNTERCLOCK-
WISE LOOSENS THE CHAIN on the guide bar.
3.
After adjustment and while wearing heavy duty work
gloves, move the saw chain back and forth on the
guide bar to be sure the chain moves freely and is in
proper mesh with sprocket.

WARNING: Whenever handling the saw

against sharp cutting edges.

CAUTION: If a chain is TOO LOOSE or TOO
TIGHT, the bar chain and saw bearings will
wear more rapidly. Study Fig. 4 for informa-
tion concerning correct cold tension (A), cor-
rect warm tension (B), and as a guide for
when saw chain needs adjustment (C).
CAUTION: If the chain is too loose, more
than 3mm after applying down force with fin-
ger, as shown in Fig. 4. It needs to be adjust-
ed, otherwise the stopping time might be over
the limit.

< 2mm
NOTE : IF the chain is difficult to rotate or if it binds on the
guide bar, too much tension has been applied and must
be adjusted. To decrease tension, turn the adjustment
screw counterclockwise slowly. Move the chain back and
forth until it moves freely.
4.
Holding the nose in upper position, securely tighten
the bar retaining nuts (70 inch lbs.)
•
FILLING OIL TANK
Using a funnel, fill oil tank with Texas Chain, Bar and
Sprocket oil. Wipe up any spills. Make sure no dirt gets
into the oil tank.
The saw chain requires lubrication while in use to mini-
mize friction with the guide bar. The oil tank holds 200ml
of oil, enough to lubricate the chain for 15-20 minutes of
sawing.
We recommend using Texas Chain, Bar and Sprocket Oil,
which contains additives to reduce friction wear and
reduce resin residue formations.
NOTE: Your chain saw is equipped with an Automatic
Oiler system and is the ONLY source of lubrication for the
bar and chain (Fig. 6)

CAUTION: The oil tank level should be fre-
quently checked during operation to avoid
starving the bar and chain of lubrication.

OPERATION INSTRUCTIONS
•
TO START SAW
1. Make sure the chain brake IS DISENGAGED. The
motor will not start if the chain brake is in the
ENGAGED position. Disengage the chain brake by
pulling backward toward the motor (Fig. 7A).
2. An extension cord retainer is built into the switch han-
dle that prevents the extension cord from pulling out of
the handle. To use this feature, simply double the
extension cord, about a foot from the end, and insert it
into the end of the handle. Hook the loop formed by
doubling the cord over the tab. Gently tug on the cord
to ensure that it is firmly retained in the saws handle.
Plug the receptacle end of the extension cord into the
tool;s power supply cord. (Fig. 7B)
3. Grip the saw with both hands, left hand holding the
front /handle (DO NOT HOLD CHAIN BRAKE ) and the
right hand holding the rear handle. Thumbs and fingers
should encircle both handles (Fig. 7C).
4. With your RIGHT THUMB, push the LOCK/OFF button
(C) forward at end the top of the rear handle, and at the
same time squeeze the trigger. To stop the saw,
release the trigger (Fig. 7D).
NOTE: It is not necessary to maintain pressure on the
LOCK/OFF button once the trigger is squeezed and the
motor is running. The LOCK/OFF button is a safety device
to avoid accidental starting.
•
TO STOP MOTOR
The saw motor will automatically stop when the trigger is
released. The LOCK/OFF button will have to be
depressed and the trigger squeezed to restart the motor.
•
CHAIN AND BAR LUBRICATION
Adequate lubrication of the saw
chain during cutting operations is
essential to minimize friction with
the guide bar.
Your chain saw is equipped with
an automatic oiler system. The
oiler automatically delivers the
proper amount of oil to the bar
and chain. There is no flow
adjustment.
The oil tank level can be checked in the inspection win-
dow (A) provided on the right side of the saw. Tank is full
when oil is at the top of the slot (Fig. 8).
WARNING: Ensure the extension cord is of
the proper size and type for your saw.
