Read carefully the data written on the Technical 
Data sheet that you will find in the package 
together with your product.  

Power supply

Extension cords 

ƒ

when you have to operate with your chainsaw far 
from an electrical outlet, you can use an extension 
cord. If you use it make sure that the section of the 
cord is suitable and that the cord is provided with 
ground conductor; 

ƒ

the extension cord (made up of cable, plug and 
socket) must be suitable for outdoor use. It is better 
if the cord is made of rubber and it is H07RN-F; 

ƒ

follow the chart shown in figure 11 on this manual 
for the choice of the right section of the conductors; 

ƒ

if you use more than one extension cord make sure 
that every cable in each extension cord has a 
section not lower than the value shown on the chart 
in figure 11, considering the total length of the 
extension cords;  

ƒ

remember the longer an extension cord the higher 
the drop in voltage. This causes loss of rpm and 
therefore cooling as well as loss of power 

operating your chainsaw. Don’t use extension cords 
if you have to operate too far from the electrical 
outlet. 

Mechanical chain brake 

Your electric chainsaw is endowed with a mechanical chain 
brake. The chain brake is a safety device for stopping or 
locking the saw chain when kickback occurs. The 
mechanical chain brake is operated by the chain brake lever 
(C). The chain brake lever has two positions (fig.5):  

ƒ

“open”, in back position, where the tool can work; 

ƒ

“active”, in front position, where the chain in blocked. 

The chain brake is activated when the hand or the wrist of 
the operator put pressure on the chain brake lever until it 
snaps into “active” position. When the chain brake operates 
the saw chain blocks. 

The resume cutting operations, release the ON/OFF switch 
and pull the chain brake lever in “open” position. 

ON/OFF switch

See figure 4 in order to understand how to use the switch 
(figure 2 E).  

Your switch is equipped with a safety lock device. With this  
device you can switch on the motor only if you follow first 
step I and than step II, as shown in figure 4. This prevents 
the chainsaw from  starting accidentally. 

Caution:  after switching off, the machine will 
not be idle immediately. 

Checks and precautions to avoid 
structural damages and damages to 
objects 

Before starting any cutting activity, talk with the construction 
manager or the planner in order to make sure that the cut 
doesn’t:  

ƒ

make any damage to the structure of the building 
and doesn’t change the structural characteristics of 
the construction; 

ƒ

damage any water or gas pipeline or any electrical 
circuits. 

Chain choice 

Your CARDI electric chainsaw is designed to cut perforated 
masonry (perforated bricks), Poroton, tuff, Gasbeton, Ytong, 
Alveolater, Siporex, expanded clay blocks, solid bricks etc. 
using proper chains. 

Warning: Do NOT use wood saw chains or 
other kind of chains not proper for your 
electric chainsaw. Failure to follow this 
warning may result in serious personal 
injury.

Ask your dealer about the best chain for your application. 
The chain must have the features listed on the Data sheet 
supplied with your electric chain saw.

Use of chains with inappropriate features can result in 
kickbacks, vibrations and loss of control causing serious 
injury. 

Check the chains before use. Do not use damaged chains. 

Chain and guide bar mounting and 
replacement

Before mount or replace the guide bar (A) or the chain 
(B), unplug the plug from the socket. Use proper 
safety gloves in order to avoid injuries touching the 
chain. Put the electric chainsaw on a clear and stable 
surface. 

To work properly the chain must be lubricated by chain oil. If 
you are using for the first time a new chain, soak for one 
hour in chain oil prior to mounting it. 

It better to use always the same chain oil type to avoid 
different oils mixes that can undermine the lubricant 
efficiency and reduce the chain working life. 

Never use waste oil, heavy oil or excessive fluid oil. 

For chain mounting and replacement refer to figure 7. 
Operate as follow: 

ƒ

loosen and remove the carter-tightening nuts (7/A) 
using the key provided; 

ƒ

remove the carter (7/B); 

ƒ

remove the upper steel plate (7/C); 

ƒ

fit the chain around the guide bar being careful to 
rotation sense of the teeth (fig.8) and keeping it taut 
so that it adheres to the bar in order to have the 
chain savings in the back of the guide bar (7/ D); 

ƒ

fit the bar around the drive sprocket and fit the bar 
with the pins. Be sure that the chain tightener pin is 
fitted in the tightening hole (7/E); 

ƒ

hold the guide bar and fit the carter (7/F);
