SAFETY PROTECTIVE CLOTHING
Major cases of electric chainsaw accidents
happen when the chain hits the operator.
While working with the electric chainsaw,
always use safety protective approved
clothing.
The use of protective clothing does
not eliminate injury risks, but it reduces the
injury effects in case of accident. Consult
your trusted supplier to choose an adequate
equipment.
The clothing must be proper and not an
obstacle. Wear adherent anti-cut clothing.
Efco
anti-cut jackets, dungarees and leggings are
the ideal.
Do not wear clothes, scarves, ties or
bracelets that can stuck into woods or twigs.
Tie up and protect long hair (example with
foulards, cap, helmets, etc.)
Safety shoes or boots having skid-proof sole
and anti-piercing insert.
Wear protective helmet in places where there
can be falling objects.
Wear protective goggles or face screens!
Use protections against noises; for example
noise reduction ear guards or earplugs.
The use of protections for the ear requests
much more attention and caution, because the
perception of danger audio signals (screamings,
alarms, etc.) is limited.
Wear anti-cut gloves.
Efco offers a complete range of safety
equipments.
4. FITTING THE BAR AND CHAIN
WARNING - Unplug the power cord
from the mains socket outlet before
performing maintenance work. Always wear
work gloves during assembly procedures. Use
only bars and chains recommended by the
manufacturer (page 33).
- Pull the cover (Fig.4) towards the front grip
to check that the chain brake is not engaged.
- Turn the knob (A, Fig.5) anti-clockwise and
remove the guard (B).
- Ensure chain tensioner disk (C) on bar (E) is
set to the correct position; turn it anti-
clockwise if necessary (Fig.6).
- Fit the chain (D, Fig.7) with the cutting edges
facing the direction of run and insert it into
the channel on the bar.
- To assemble the bar (E, Fig.8) and chain (D),
align them with sprocket (F) and stud (G).
Wrap the chain around the sprocket and
then fit the bar over the stud. Turn disk (C)
clockwise to pre-tension the chain.
- Refit the guard (B, Fig.10) inserting the guide
(L, Fig.9) into its location and lightly
tightening the knob (A, Fig.10). Do not
tighten the knob fully; first, you must tension
the chain. While tightening the knob rotate
ring (H) back and forth to cause it to engage
correctly with disk (C) on the bar.
NOTE:
chain (D) is not yet tensioned.
Chain tensioning
Always check the chain tension before using
the chainsaw and after making the first few
cuts. Regularly check the chain tension when
using the tool. After starting to use the tool,
new chains may stretch considerably; this is to
be considered normal during the running-in
period.
WARNING - Always maintain the correct
chain tension.
An excessively slack chain
increases the risk of kickback and the chain may
ride out of the bar channel; these events can
cause injury the operator and damage to the
chain. An excessively slack chain will result in
rapid wear of chain, bar and sprocket. On the
contrary, an over tensioned chain will tend to
overload the motor with resulting damage.
A
correctly tensioned chain provides the best
cutting characteristics, optimal safety, and
long working life of the chain.
The working
life of the chain depends on correct tensioning
and correct lubrication.
- Turn the ring (H, Fig.10) until chain (D) nearly
touches the lower edge of bar (E).
- Check chain tension by lifting it with your
