may PUSH the guide bar rapidly back toward the operator.
Any of these reactions may cause you to lose control of the saw,
which could result in serious personal injury.
▪ With a basic understanding of kickback, you can reduce or
eliminate the element of surprise. Sudden surprise contributes to
accidents.
▪ Keep a good firm grip on the saw with both hands, the right hand
on the rear handle, and the left hand on the front handle, when
the engine is running. Use a firm grip with thumbs and fingers
encircling the chain saw handles. A firm grip will help you reduce
kickback and maintain cont
rol of the saw. Don’t let go.
▪ Make sure that the area in which you are cutting is free from
obstructions. Do not let the nose of the guide bar contact a log,
branch, or any other obstruction which could be hit while you are
operating the saw.
▪ Cut at high engine speeds.
▪ Do not overreach or cut above shoulder height.
▪ Follow manufacturer’s sharpening and maintenance instructions
for the saw chain.
▪ Only use replacement bars and chains specified by the
manufacturer or the equivalent.
NOTE: Low-kickback saw chain is chain that has met
the kickback performance.
WARNING: Kickback can lead to dangerous loss of
control of the chain saw and result in serious or fatal
injury to the saw operator or to anyone standing
close by. Always be alert. Rotational kickback and
pinch-kickback are major chain saw operational
dangers and the leading cause of most accidents.
SAFETY WARNINGS GASOLINE
WARNING: Use extra care in handling fuels.
They are flammable and the vapours are explosive.
The following points must be observed:
▪ Use only an approved container.
▪ Never remove the fuel cap or add fuel with the power
source running. Allow engine exhaust components to
cool before refuelling.
▪ Do not smoke.
▪ Never refuel the machine indoors.
▪ Never store the machine or fuel containers inside,
where is an open flame, such as a water heater.
▪ If fuel is spilled, do not attempt to start the power
source, but move the machine away from the area of
spillage before starting.
▪ Always replace and securely tighten the fuel cap after
refuelling.
▪ If the tank is drained, this should be done outdoors.
ASSEMBLY
Danger:
Do not start the engine until the saw is fully assembled.
Caution:
Wear protective gloves at all times when handling the
chain.
Installing the guide rail and saw chain (Fig. 2A-2G)
1. Disengage the chain brake by pushing the front hand guard (6)
towards the front handle (7). (Fig. 2A)
2. Remove the chain bar cover (A) by loosening the nut (19) (Fig.
2B)
3. Place the guide rail (2) into the mounting on the chainsaw (Fig.
2C).
4. Place the chain (3) around the drive wheel (C) (Fig. 2E). Check
that the direction of rotation of the chain (3) is correct. The cutter
links (B) must be aligned as shown in Fig. 2D.
5. Place the chain around the chain bar. (Fig.2E)
6. The chain drive links (3) must slide fully into the groove which
runs around the cutter bar (D) and also between the teeth on the
drive wheel (C). (Fig. 2E)
7. Turn the chain tensioning screw (20) counterclockwise until the
bolt (E) is at the end of its travel. (Fig. 2B/2F)
8. Install the bar cover (A).
Important!
The bolt (E) on the chain tensioning mechanism must
snap into place in the hole (G) in the guide rail. (Fig. 2G).
To ensure that happens, slide the guide rail (2) forwards and
backwards slightly when you mount the bar cover (A). Hand
tighten the nut (19).
Adjusting the chain tension (3A/3B)
Before adjusting the chain tension, make sure that the engine is
switched off .
1. Push the tip of the guide rail (2) upwards slightly and adjust the
chain tension using the chain tensioning screw (20).
(Fig. 3A) The chain is set to the optimal tension when
the chain (3) on the underside at the middle of the guide
rail (2) is as shown in Fig. 3B.
2. Tighten the nut (19) while applying slight pressure to
the tip of the bar.
3. Carry out a functional check. Pull the chain (3) by
hand once all the way around the guide rail (2). If the
chain (3) is hard to pull around the guide rail (2) or if it
jams, the tension is too tight.
If that is the case, make the following slight adjustment:
1. Loosen the nut (19) and hand tighten it again.
2. Reduce the chain tension by turning the chain
tensioning screw (20) counterclockwise. Only make
small adjustments at a time and always pull the chain (3)
backwards and forwards on the guide rail (2) to see if the
chain moves smoothly (3) but still fits tightly.
Note:
If the chain (3) is too loose, turn the chain
tensioning screw (20) clockwise.
3. If the chain tension is adjusted to the optimal setting,
tighten the nut (19) while applying slight pressure to the
tip of the bar.
A new saw chain will stretch, so it is important to
readjust the chain at short intervals (around 5 cuts)
when you first start using it. The intervals get longer
as operating time increases.
Note:
If the saw chain (3) is TOO LOOSE or TOO
TAUT, the drive wheel, chain bar, chain and crank shaft
bearing will suffer premature wear. Fig. 3B shows the
correct tension A (when cold) and tension B (when
warm). Fig. C shows a chain that is too loose.
OPERATION
Fuel and lubrication
Fuel
Use regular grade unleaded gasoline mixed with 1:25 custom 2-
cycle engine oil for best results.
Mixing fuel
Mix fuel with 2 cycle oil in an approved container. Shake container
to ensure thorough mix.
Note:
Never use straight gasoline in your unit. This will cause
permanent engine damage and
void the manufacturer’s warranty
for that product.
Never use a fuel mixture that has been stored for over
90 days.
Note:
If 2-cycle lubricant is to be used, it must be a
premium grade oil for 2-cycle air cooled engines mixed
at a 1:25 ratio. Do not use any 2-cycle oil product with a
recommended mixing ratio of 1:100. If insufficient
lubrication is the cause of engine damage, it voids the
manufacturer’s engine warranty for that occurrence.
Recommended fuels
Some conventional gasolines are being blended with
oxygenates such as alcohol or an ether compound to
