Thermal overload protection

To prevent overheating under an extreme long-

term load, the safety electronics switch the motor

into cooling mode when the critical temperature

is reached. The machine cannot be loaded, and

it runs at reduced RPM. After cooling, the tool is

once again prepared for operation and can be fully

loaded in about 3 – 5 minutes. If the tool gets hot

while running, the heat protection reacts corre-

spondingly earlier.

RPM selection

Using the RPM regulator [1-14], it is possible to

preselect the RPM continuously:

Level 1: 2200 min

–1

Level 4: 3600 min

–1

Level 2: 2600 min

–1

Level 5: 4100 min

Level 3: 3200 min

Level 6: 4600 min

8 Preparation for use

8.1 Mounting the chain

WARNING

When mounting the chain make sure it seats cor-

rectly. The cutting teeth must be positioned in the

direction that conforms to the chain rotation, i. e.,

the mark shown on the body of the saw.

When the ISP 330 EB is delivered, the chain is not

mounted on the guide bar. Remove the chain sprock-

et cover [2-1] by rotating the fastening wheels

[2-2] counter clockwise, as shown in Fig. [2]. Put a

new chain [2-3] on the guide bar [2-4] and insert

it into the machine. Maintain the proper position

of the cutting teeth, according to the direction of

rotation. The direction of rotation is indicated by

an arrow on the body of the machine, and under

the chain sprocket cover there is a symbol show-

ing how the chain should be mounted. Place the

guide elements of the chain onto the chain sprocket

[2-8] and turn using the chain adjustment wheel

[2-9] (when rotated clockwise as seen from above,

the pin moves upwards and releases; when ro-

tated counter clockwise as seen from above, the

pin moves downward) so that the opening on the

guide bar [2-5] snaps into the tension bolt [2-6].

Then put the chain sprocket cover [2-1] on the

clamping bolt [2-7] and tighten by rotating the

fastening wheel [2-2] clockwise. Before tightening

it ﬁ rmly, tension the chain correctly, as described

in Section 11.1.

8.2 Filling the oil reservoir

When the ISP 330 EB is delivered, the lubrication

oil reservoir is empty. Before using the machine,

you must ﬁ ll the tank with chain oil to prevent

damage to the oil feed pump. If the machine is

operated with an insufﬁ ciently ﬁ lled oil reservoir

or with a dysfunctional lubricating system, the oil

feed pump will be damaged, as well as the tool’s

entire cutting assembly!

The oil reservoir cap [1-9] has an opening with a

one-way suction valve for air pressure compen-

sation. If you use the machine in other than the

vertical position, the chain may not get lubricated.

The outlet of the oil reservoir is located down at

the back, and when the machine rotates, the pump

is not able to suck up the oil. The quantity of oil

in the reservoir is indicated by the level in the oil

gauge [1-8].

8.3 Electrical connection

WARNING

If the tool is used with an incorrect power supply,

there is a risk of injury.

The ISP 330 EB insulation saw can only be con-

nected to a single-phase power supply with 230V/

50–60Hz alternating current. The machine has a

class II protective covering according to EN 60 745-1

and has noise suppression according to EN 55 014.

Before operating the machine, make sure that the

voltage of the socket corresponds to the voltage

information stated on the label of the machine.

The portable cord can be extended in the following

manner, if necessary:

- Length 20 m, cross-section of wires 3 × 1.5 mm

- Length 50 m, cross-section of wires 3 × 2.5 mm

Use only appropriately marked extension cords

intended for use outdoors.

9 Operation

WARNING

Before performing any maintenance work on the

tool, always remove the plug from the electrical

mains socket.

Check that the information on the manufacturing

label complies with the actual power supply volt-

age.

Equipment marked with 230 V can also be con-

nected to 220 V / 240 V.

Check that the plug type is the same as the socket

type.

9.1 Switching on and off

Before switching the machine on, tighten all clamp-

ing and ﬁ xing bolts. Handle the machine with both

hands, and put it on the cutting piece so that the

chain is loose and will not stick inside the cut after

activation.

To turn on

Press the unlocking button [1-1] on the top of the

handle and hold it; then press the motor switch

button [1-2].

To turn off

Let up on the motor switch button [1-2]. The un-

locking button [1-1] will return to its initial posi-
