Connection To The Mains Supply; Switching On/Off; Working With The Chainsaw - IKRA HESI 750 Instrucciones De Manejo

6.2 Connection to the mains supply

• Connect the mains cable to a suitable extension
cable. Make sure that the extension cable is designed
to accommodate the power of the chain saw.
• Secure the extension cable against tractive forces
and accidental unplugging as shown in (Fig.10).
• Connect the extension cable to an earthed safety
socket installed in accordance with regulations. We
recommend the use of a cable in a signal colour (red
or yellow). This reduces the risk of accidental damage
from the chainsaw.
Recommendation
Only connect the device to a power source that is pro-
tected via a residual current protective device (RCD) with
a maximum release current of 30 mA.

6.3 Switching on/off

Switching on
• Hold the chainsaw firmly with both hands on the hand-
le (thumb under the handle).
• Press and hold the switch lock (Fig.11).
• Switch the chainsaw on with the on/off switch (3). The
switch lock (14) can now be released again.
Switching off
• Release the on/off switch (3). Always pull out the
mains plug when discontinuing the work.

7. Working with the chainsaw

7.1 Preparation
Before each use, check the following to ensure safe
work:
Condition of the chainsaw
Before beginning work, inspect the chainsaw for damage
to the housing, the mains cable, the saw chain and the
guide bar. Never use an obviously damaged machine.
Oil tank
Fill level of the oil tank. Also check whether there is
sufficient oil available while working. Never operate the
saw if there is no oil or the oil level has dropped below
the minimum oil level mark in order to prevent damage
to the chain saw. On average, an oil filling is sufficient
for 10 minutes of operation, depending on the duration
of pauses and the stress.
Saw chain
Tension of the saw chain, condition of the cutters. The
sharper the saw chain is, the easier and more manage-
able the chain saw is to operate. The same applies for
the chain tension. Also check the chain tension at least
once every 10 minutes while working in order to increase
safety! New saw chains, in particular, tend to have a
higher degree of elongation.
Protective clothing
Make absolutely sure to wear the appropriate, close-
fitting protective clothing, such as chainsaw-protective
pants, gloves and safety shoes.

Hearing protection and protective goggles
Wear a safety helmet with integrated hearing protection
and a face guard. This provides protection against falling
branches and recoiling branches.
