The battery benefits from the "α UP-Innovation RURIS" function. This function
helps the battery when it reaches the critical discharge threshold. Ruris came up
with an innovation in the system of cells inside the battery, through which the
battery can be recharged after a long period of time in which it has been
discharged. Thus, RURIS users can enjoy the reliability and innovation of RURIS.
After storage, charging is recommended at an interval of 6 months - 1 year
5. KICKBACK SAFETY MEASURES
KICKBACK can occur if the TIP or END of the blade
touches any object, or if the wood tightens and catches the
chain in the cut.
Contact with the tip can sometimes produce an extremely rapid reaction, throwing the
blade up and back towards the operator.
LOCKING the chain along the BOTTOM of the blade can PULL the saw forward toward
the operator.
LOCKING the chain along the TOP of the blade can quickly PUSH the saw back toward
the operator.
Any of these reactions can cause the saw to run out of control, causing serious injury.
A basic understanding of recoil can reduce or eliminate the surprise effect. Surprise is
one of the causes of accidents.
While operating the chainsaw, hold the saw firmly with both hands, with the right hand on
the rear handle and the left hand on the front handle. Grip firmly with your fingers around
the handles of the chainsaw. The firm grip helps reduce kickback and keep you in control
of the saw. Don't let him go.

EN
12
Check that there are no obstacles in the area where you are cutting. Do not allow the tip
of the blade to come into contact with trunks, branches, or any other obstructions that
may be struck while using the chainsaw.
Don't stretch too far or cut above shoulder level.
Follow the manufacturer's instructions for chain sharpening and maintenance.
Use only replacement blades and chains specified by the manufacturer or equivalent.
NOTE: Low recoil chains are the ones that fall under recoil performance.
WARNING: Kickback can cause the chainsaw to run dangerously out of control and
cause serious injury or death to the operator or bystanders. Be alert at all times. Kickback
or kickback are the main hazards when using a chainsaw and the main cause of most
accidents.
Be careful at:

6. INSTALLATION GUIDE
Wear gloves when handling the blade and chain; these pieces are sharp.
Do not touch or adjust the chain with the
engine running. The chain is very sharp;
Always wear gloves when performing chain
maintenance to avoid injury.
Using the chain and blade (Fig. 4-5)
Disconnect the chainsaw battery.
Turn the lock knob on the chain cover
counterclockwise and remove the knob and
sleeve.
Remove the chain cover.
Stretch the chain in the form of a loop and
straighten the twisted areas. The cutting teeth
must be pointed in the direction of rotation of
the chain. If they are facing the other way, turn
the loop.
Place the chain drive spurs in the bar
groove as shown.
Position the chain so that there is a loop
on the back of the blade.
Hold the chain in place on the blade and
place the loop around the sprocket.
Secure the blade flush with the mounting surface so that the blade pins are on the long
slot of the blade.

EN
14
NOTE: When placing the bar on the bar pins, make sure the adjusting pin is inserted into
the hole in the bar for chain tensioning.
Install the chain cover.
Refit the sleeve and chain cover locking bolt; Turn the knob clockwise to tighten the drive
pinion cover. The blade must still be free to move for tension adjustment.
Loosen the chain completely by turning the tension wheel clockwise until the chain is
firmly seated on the bar with the drive spurs in the bar groove.
Lift the tip of the guide blade to check for
bending.
Release the tip of the guide bar and turn the
chain tension wheel half a turn clockwise.
Repeat the procedure until there is no more
bending.
Hold the tip of the guide bar and tighten the
chain cover lock bolt. The chain is properly
tensioned when there is no more bending on the bottom of the guide bar, it sits securely
and can be turned by hand without resistance or binding.
NOTE: If the chain is too tight, it will not turn. Loosen the chain cover lock knob slightly
and turn the chain tensioner wheel counterclockwise a quarter turn. Raise the tip of the
guide bar and tighten the chain cover lock bolt. Make sure the chain rotates without
locking.
Lubricating oil for the chain. (Fig. 6)
Before starting the chainsaw, the tank must be filled with RURIS M-POWER chain oil.
Never use waste oil to lubricate the chain.

EN
15
To supply the chain oil tank of the chainsaw, unscrew the supply plug. Avoid getting
contaminants into the oil during fueling. The oil level can be checked through the level
glass.
7. USER GUIDE
Make sure that :
•Fully charge the battery before first use.
•Fill the tank with oil for lubricating the chain.
•Check that the cutting equipment is properly mounted and secured.
•Prolonged exposure to noise pollution can lead to permanent hearing damage.

position.
7.2 ACTUATION OF THE CHAIN BRAKE
Before each use, check the proper operation of the chainbrake (Fig. 9). Engagethe chain
brake by rotating your left hand around the front handle, pushing the chain brake
lever/hand guard towards the blade with the back of your hand as the chain rotates
rapidly. Keep both hands on the saw handles (1) at all times.

EN
17
Return the chain brake to the RUN position by grasping the top of the chain brake lever
/ hand guard and pulling toward the front handle (2).
8. GENERAL INSTRUCTIONS FOR CUTTING
felling
Felling is the term for cutting down a tree completely. Small trees up to 15-18 cm (6-7
inches) in diameter are usually felled in a single cut. Larger trees require the cutting of
stakes. The stakes determine the direction in which the tree will fall.
Felling trees:
Warning: Before starting to cut, an escape route (A) must be provided and cleared. The
escape route must extend backwards and diagonally, opposite the direction of fall, as in
Fig. 10 a.
Caution: When felling a tree on sloping ground, the chainsaw operator must remain
upstream, as it is very possible for the tree to roll downhill after felling.
Note: the direction of fall (B) is controlled by the plug. Before making a cut, study the
position of larger branches and thenatural inclination of the tree to determine the direction
of the tree's fall.

EN
18
Warning: Do not fell trees in high or variable wind conditions or if there is danger of
damage. Consult a forestry specialist. Do not cut trees if there is a danger of hitting power
lines; notify the electricity company before cutting.
General recommendations for felling trees:
In general, felling consists of two main cutting operations, tapping (C) and making the
felling cut (D). First make the cut from the top of the plug (C) on the side of the shaft
facing the direction of fall (E). Be sure not to cut too deep into the trunk.
The plug (C) must be deep enough to create a hinge (F) thick enough and strong enough.
The plug must be wide enough to direct the fall of the tree for as long as possible.
WARNING: Do not pass in front of covered trees. Make the felling cut (D) on the opposite
side of the shaft and 3 - 5 cm (1.5 - 2.0 inches) above the edge of the plug (C) (Fig. 10
b)
Do not cut through the trunk completely. Always leave a hinge. The hinge guides the
shaft. If the trunk is completely cut, the direction of fall is no longer controlled.
Insert a wedge or felling lever into the cut long enough before the tree becomes unstable
and begins to move. This prevents the blade from getting stuck in the felling cut if you
misjudged the direction of the fall. Before pushing the downed tree, make sure there are
no bystanders in its range.

EN
19
Warning: Beforemaking the finalcut, double-check that thereare no bystanders, animals,
or obstacles in the area.
Knockdown Cut:
Use wooden or plastic wedges (A) to avoid catching the blade or chain (B) in the cut. The
feathers also have the role of controlling the fall (Fig. 10c)
If the diameter of the cut wood exceeds the length of the blade, make two cuts, as in the
figure (Fig. 10d).
WARNING: Whenthe felling cut approaches the hinge, thetree should begin to fall. When
the tree begins to fall, remove the saw from the cut, stop the engine, lower the chain saw
and leave the area on the escape route (Fig. 10a).
Cleaning of branches
Delimbing is the process of removing branches from a downed tree. Do not remove
supporting branches before sectioning (cutting) into pieces (Fig. 11).

EN
20
Branches under tension must be cut from the bottom up to avoid bending the chain rail.
WARNING: Do not cut branches while standing on the tree trunk.
Sectioning
Sectioning means cutting a fallen trunk into pieces. Ensure stable footing and sit
upstream of the trunk when cutting on sloping ground. If possible, the trunk should be
supported so that the end to be cut does not rest on the ground. If the trunk is supported
at both ends and must be cut in the middle, make a cut down to the middle of the trunk,
then cut underneath. This will prevent the blade and chain from getting caught in the
trunk. When sectioning, avoid cutting with the chain into the ground, as this leads to rapid
blunting of the chain. When sectioning on a slope, always sit upstream.
Trunk supported along the entire length. Cut from above (top sectioning), avoiding cutting
into the ground (Fig. 12 a).
