Care and maintenance

8.1 Care and maintenance of the tool
The tool must be unloaded (remove the gas can and fastener from the tool) before carrying out cleaning
or maintenance. Completely remove the battery, gas can and nail strip from the tool.
1. Clean the outside of the power tool at regular intervals with a slightly damp cloth.
2. Never operate the tool when the ventilation slots are blocked. Clean the ventilation slots carefully using
a dry brush.
3. Do not permit moisture or foreign objects to enter the interior of the tool or the battery.
4. Remove the tool from its case and allow it to dry out if moisture has entered the tool. To do this, remove
the battery and keep the gas can compartment cover at the rear in the open position.
5. Always keep the grip surfaces of the appliance free from oil and grease.
6. Do not use a spray, steam pressure cleaning equipment or running water for cleaning.
7. Do not use cleaning agents containing silicone.
8. Make sure that there is no oil or grease on the battery contacts.
8.2 Repair of the power tool
▶ Regularly check all external parts of the tool for damage and check that all controls are in full working
order. Do not operate the tool if parts are damaged or if controls are not in full working order.
If damage occurs, have the tool repaired by Hilti Service only.
8.3 Cleaning the appliance
The tool needs regular maintenance and cleaning. We recommend that the tool is cleaned, at the latest,
after making 40,000 fastenings. The tool should also be cleaned if malfunctions occur frequently, e.g.
misfiring or firing without a nail being driven.
▶ Clean the power tool at regular intervals. Use only Hilti products or products of comparable quality for
cleaning.
▶ The required materials, tools, and documentation are available from Hilti as accessories.
▶ You can have the necessary maintenance work carried out by Hilti. To do so, contact your local Hilti
branch.
8.4 Cleaning the piston
Dirt and remains of the nail collation strip may hinder piston movement. Malfunctions occur increasingly, i.e.
the tool is triggered but no fastener is driven. In this case, the piston should be cleaned as follows:
1. Remove the battery, the gas can and the fasteners from the tool.
2. Use a screwdriver to push the piston back as far as it will go.
3. Spray cleaning fluid generously into the tool nosepiece.
4. First replace the battery and then the gas can.
5. Pull the nail pusher back by hand and then trigger the tool five times, without driving fasteners, with the
nosepiece pressed against a suitable surface (see the section headed "Intended use").
6. Reload the fasteners and continue working with the tool in the usual way.
7. If necessary, repeat steps 1-6.
