WW90 II

WORKING AT LOW TEMPERATURES

We do not recommend using this gas powered tool at 
temperatures below -7°C (19°F). Low temperatures 

reduce  the  gas  combustion  efficiency  and  battery 

performance.

MEASURES IN THE EVENT OF RAM JAMMING 
IN THE MUZZLE

ƒ

It may sometimes happen that a piece of a nail 

tape causes the ram to jam inside the muzzle, in 
which case:

ƒ

Disconnect the battery and the gas container 

from the nailer, and remove the remaining nail 
tape from the magazine.

ƒ

Place the nailer on a stable surface with the 

muzzle facing upwards.

ƒ

Position a type PH2 screwdriver of appropriate 

length above the muzzle hole and gently hit it with 
a hammer to unlock the jammed ram (as shown in 
the photograph). The unjammed ram should move 
smoothly into the nailer away from the muzzle.

ƒ

Remove the blocking piece of tape from the 

muzzle.

ƒ

We recommend blowing the nailer muzzle 

through with compressed air.

ƒ

Finally, make sure that the ram has fully retracted and 

reached its extreme position, since otherwise, the 
first time you try to drive a nail, the tool may cause 
what is referred to as a misfire, meaning that the 
nailer does not pick up a nail and the ram directly hits 
the material into which the nail was to be driven. Each 
subsequent nail ejection should proceed correctly.

Before performing any inspection or 

maintenance,  switch  the  device  off  by 

disconnecting it from the power supply (battery), 
and disconnect the gas container.   

General maintenance 

ƒ

The persons responsible for making sure that the 
tool is maintained in a fully operational condition 
enabling safe use are the employer and the tool 
operator.

ƒ

NEVER use the tool if there is any doubt with 
regard to its technical condition.

ƒ

Regularly check that all mounting screws are 
properly tightened. If any of the screws are loose, 
tighten them immediately to avoid danger. Any 
damage not resulting from improper operation 
should only be repaired by the manufacturer’s 
authorised service centre in order to avoid risks 
and losing warranty due to tampering with the 
device’s internal components.

Do not use solvents or other aggressive 
chemical compounds to clean the device, 

as this may cause damage to its rubber and plastic 
components.

Lubrication and cleaning

ƒ

Keep the tool properly cleaned according to the 
enclosed cleaning and maintenance instructions. 
A fully operational device does not require 
additional lubrication of external moving parts, 
such as safeguard A. The gas which contains oil 
provides for lubrication of the tool’s internal 
components.

ƒ

Use only the compounds recommended by the 
manufacturer for cleaning.

ƒ

Pay special attention to the handle cleanliness. A 
dirty handle may compromise the grip. This may 
lead to losing control of the device.

Storage

Store the battery-powered nailer and its accessories 
in a dry and safe place, out of children’s reach. 
Store the device with the battery pack removed. 
Also remember not to store discharged batteries 
for a prolonged time, since it may damage them. 
Batteries should be charged on an ongoing basis, 
as soon as they are discharged, which extends their 
service life.

MAINTENANCE

Symptoms

Remedies

The nailer LED is lit red and the 

tool is not working.

ƒ

Low battery.

ƒ

Replace the battery with a fully charged one.

The tool operates normally but 

does not drive fasteners flush with 

the working surface.

ƒ

Set a larger driving depth using the tool’s knob.

ƒ

Clean the cylinder with proper cleaner.

ƒ

Check the battery status and replace it if needed.

ƒ

Wood in which fixing is attempted is too hard or wet. Using different na-

ils is recommended.

The fan does not work and the 

LED indicator is lit red.

ƒ

The battery is dead. Replace the battery with a fully charged one.

ƒ

If none of the above measures solve the problem, return the tool to the ne-

arest service centre.

The battery cannot charge, or 

the battery charger is heating up 

when charging.

ƒ

Replace the battery. If this has solved the problem, the battery is dama-

ged or used up.

ƒ

If the battery is functioning normally when installed on the tool but can-

not be charged using the charger, replace the charger.

Battery charger is heating up, pro-

duces abnormal noise or smoke.

ƒ

The battery charger is damaged and unfit for further use. Unplug the 

battery charger immediately and replace it with a new one.

Safeguard A is locked and cannot 

be fully pressed down, which 

makes it impossible to operate 

the tool.

ƒ

The contact element is bent or some dirt is stuck in the track of the safe-

guard mechanism. Clean the safeguard mechanism track. Repair or re-

place the contact element by returning the device the service centre.

ƒ

Locking mechanism is active. Charge the nailer by inserting a new nail 

tape into the magazine.

ƒ

Check if the ram has not got jammed inside the muzzle, and if so, follow 

the relevant instructions provided in this operation manual.

The tool does not operate, but the 

green LED is on and the fan works.

ƒ

The gas container is empty or damaged. Replace it with a new and non-

-defective one.

ƒ

The spark wire is loose. Check the spark wire by removing the cap.

ƒ

The spark plug is dirty. Clean the spark plug.

ƒ

If none of the above measures solve the problem, return the tool to the 

nearest service centre.

The tool seems to work normally, 

but fixing is impossible.

ƒ

Wrong type of fasteners is used. Change fasteners with correct ones.

ƒ

The cylinder needs cleaning.

ƒ

A fastener is jammed. Clean the jammed fastener before attempting to

position.

ƒ

Safeguard A (clamp) is bent or dirty. Check safeguard A, and repair or re-

place it, if necessary. Clean the safeguard mechanism track.

return to its initial position, and 

misfire frequency has increased 

above the average.

ƒ

Check and replace the complete battery pack.

ƒ

Clean the tool using an adequate cleaning agent.
