Safety Devices; Status Indicator; Indication Of Battery Charge Status - Hilti BX 3-ME Manual De Instrucciones

if the appropriate fasteners are used. Use only approved fasteners in conjunction with the fastener guide
designed for use with these specific fasteners (see "Technical data" section).
The fastening tool, battery and fasteners form a single technical unit. This means that trouble-free fastening
can be ensured with this fastening tool only when it is used in conjunction with the Hilti fasteners specially
designed and manufactured for it and with the batteries and chargers recommended by Hilti. The fastening
and application recommendations made by Hilti apply only when this condition is observed.
▶ The fastening tool is for hand-held use only.
▶ Misuse of the fastening tool must be ruled out. Misuse of the fastening tool includes triggering in
single-fastener mode without a nail inserted in the fastener guide, driving nails into very soft materials
(e.g. wood), driving single nails when the tool is set up for magazine operation, and driving nails into
materials that are too hard (e.g. high-strength steel or very hard natural stone).
▶ Use only Hilti Li­ion batteries of the B 22 series with this product.
▶ Use only Hilti battery chargers of the C 4/36 series to charge these batteries.

3.3 Safety devices

When using the nail magazine, the nail detection feature prevents triggering without a nail loaded, which
could damage the fastening tool.
The contact pressure safety device is intended to prevent the free flighting of nails (i.e. actuation and driving
a nail when the nosepiece is not in contact with the workpiece). When using a nail magazine, the tool can be
pressed against the surface and triggered only when a nail is loaded in the tool.
To use the tool in single-fastener mode, the single-fastener mode switch must be pressed before the
fastening tool is pressed against the working surface.
3.4 Features
The fastening tool is fitted with an ergonomic, non-slip and vibration-damped grip along with a support arm
with tool hook. The tool is protected from overloading by electronic overload protection and from overheating
by temperature monitoring.

3.5 Status indicator

The status indicator provides information about the status of the fastening tool.
Status
Off
Lights green
Further status indications are described in the troubleshooting table (see → page 26).

3.6 Indication of battery charge status

When one of the battery release buttons is pressed the display indicates the battery's state of charge.
Note
Reliable indication of the charge status is not possible while a fastener is being driven or immediately
after a fastener is driven.
Status
All four LEDs light green.
Three LEDs light green.
Two LEDs light green.
One LED lights green.
One LED blinks green.
3.7 Batteries
Battery performance drops at low temperatures.
When battery performance drops, it takes longer until the fastening tool is ready to drive the next fastener
(longer than with a fully charged battery).
If you continue to operate the fastening tool after noticing a drop in battery performance, the fastening tool
will switch itself off automatically to prevent damage to the battery.
