2. Inspecting the Driver Blade
The driver blade of this power tool is a consumable part.
After nailing, if several nails stick up as shown in Fig. 28 (two or three nails per 100), it is time to change the driver blade.
As continued use may result in damage to other components such as the push lever or nose, replace the driver blade early on.
Request the dealer from whom you purchased the pin nailer or your nearest HiKOKI Authorized Service Center to change the driver blade for you.
3. Inspecting the Magazine
The inside of the magazine needs to be cleaned from time to time. Pull out the magazine cover and remove any nail adhesive, dirt, splinters or other foreign objects that have collected. (Fig. 29)
NOTEDirt in the guide groove may result in sluggish operation of the nail feeder, causing blank fi ring.
If blank fi ring occurs, remove any nail adhesive or splinters that have collected in the guide groove and apply a thin coat of the supplied oil.
4. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so may result in serious hazard.
5. Cleaning of the outside
When the power tool is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, as they melt plastics.
6. Storage
Store the power tool in a place in which the temperature is less than 40°C, and out of reach of children.
NOTEStoring lithium-ion batteries.
Make sure the lithium-ion batteries have been fully charged before storing them.
Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, signifi cantly reducing battery usage time or rendering the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to fi ve times.
If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed.

The declared vibration total value has been measured in accordance with a standard test method and may be used for comparing one tool with another.
It may also be used in a preliminary assessment of exposure.
WARNING
○ The vibration emission during actual use of the power tool can diff er from the declared total value depending on the ways in which the tool is used.
○ Identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).
