Periodical Maintenance; Sharpening The Chain - EMAK EP 100 Manual De Instrucciones

ASSEMBLY BAR AND CHAIN
The EP100 pruner comes complete with a
bar and chain assembled and adjusted in the fac-
tory.
For replacing the bar and chain, or after reshar-
pening the chain, follow this procedure:
1 - Loosen the two self-blocking nuts (A) and
remove the cover (B)
2 - Set the chain in the groove (C) of the blade and
at the same time on the driving sprocket (D);
now looking at the blade and chain together
check that the chain is set with the cutting
edges turned in a clockwise direction (E).
3 - Fix the cover where you previously set the
chain stretcher in a drawn back position (F).
4 - Make the chain stretcher pin coincide with the
hole (G) on the blade, by working on the adju-
stment screw (H).
5 - Tighten the nuts (A) on the cover with a slight
twist. Work on the chain stretching screw (H)
by turning it anti-clockwise; check the tension
of the chain so that by raising it the inside of
the chain is just visible for about 4 mm.
A correct adjustment has been made when
the chain runs freely.
Now tighten the nuts (A) as much as possible.
INSTALLATION OF THE PRUNER
Bracket (A) open; unscrew the knurled knob;
insert E
1 - Set the bell-shaped the bevel gear (B) on the
adaptor to make the reference pin (C)
coincide with the slot on the bevel gear and
the toothed pin with the central joint (D).
2 - Bring the bell-shaped bracket with the
rubber-carrying disk over the head of the
bevel gear (F). Tighten the knurled knob by
hand.
STARTING AND MAINTENANCE
1 - The pruner has a pump for lubricating the
chain which guarantees the correct quantity
during operation.
The amount that the pump delivers has been
dosed to reduce the impact with the environ-
ment to a minimum, and at the same time assu-
re the correct quantity for lubricating the chain.

2 - For best results use average viscosity oils, do
not use regenerated oil as it could damage
the pump.
3 - When starting the strimmer check that the
chain does not touch anything, even the
ground. For starting instructions refer to the
instructions provided with the machine.
4 - Advice for a correct cut. Remember not to
stand below the branch to be cut. In order to
avoid the decortication that could occur
towards the end of the cutting operation,
before starting make a few incisions in the
under part of the branch. If the branch is very
big more than one cutting operation can be
carried out to lighten the branch and better
control the job. If necessary repeat the cut.

PERIODICAL MAINTENANCE

Maintenance must be carried out while the
engine is turned off. Check that the switch of the
machine is in the "OFF" position.
Check the tension of the chain by following the
indications of point "D"
A new chain may need more frequent adjusting.
Adjustments can be made with more accuracy by
removing the pruner from the machine; this
makes it possible to carry out the maintenance of
the pruner in the workshop.

SHARPENING THE CHAIN

The chain can be sharpened while the pruner is
installed or when it has been removed from the
machine.
The removal or sharpening operation must be
carried out with the engine turned off and the
switch in the "OFF" position.
The sharpening operation must be carried out
with a disc file, 4mm in diameter (5/32"), for the
chain model N4C-BL-38E, which is installed on
F
your pruner. Get a blade guide with which to
hold the chain and alternatively sharpen on the
right and left tooth with an angle of 55°/60°. If you
do not have a blade guide, stretch the chain on
the blade using the adjusting screw so as to keep
the chain stable, and sharpen. Proceed with a flat
file to reduce the height of the limiting device
which must be inferior by 0.6 to 0.7 from the cut-
ting plane. Check the operation with a calibre.
