The Milwaukee M18 FN18GS is a cordless nailer designed for driving nails into wood or similar soft materials. It operates on an 18V battery system, providing portability and freedom from power cords, making it suitable for various job site applications. The tool is part of Milwaukee's FUEL line, indicating advanced brushless motor technology for increased power, runtime, and durability.

Function Description:

The primary function of the M18 FN18GS is to drive 18-gauge brad nails. It features two main actuation modes: Single Sequential Actuation and Contact (Bump) Actuation, allowing users to choose the most appropriate method for their task.

Single Sequential Actuation: In this mode, the user must first press the tool against the workpiece, compressing the workpiece contact, and then pull the trigger to drive a single fastener. This mode is ideal for precise nail placement and applications where controlled, individual fastening is required. The LED indicator for this mode is marked with a 'T'.
Contact (Bump) Actuation: This mode allows for faster fastening by enabling the user to pull and hold the trigger, then drive fasteners by simply pressing the tool against the workpiece. This is particularly useful for high-volume applications where speed is a priority, such as fastening large panels. The LED indicator for this mode is marked with 'TIT'.

The tool incorporates a depth of drive adjustment feature, allowing users to control how deep the nail is driven into the material. This is crucial for achieving flush finishes or specific penetration depths, depending on the application and material type. The adjustment is made by rotating a wheel located near the nose of the tool.

A reload indicator is integrated into the magazine to alert the user when the fastener supply is low (approximately 4-5 nails remaining). When the magazine is nearly empty, the workpiece contact will not compress under usual pressure, preventing further operation until more fasteners are loaded.

Usage Features:

The M18 FN18GS is designed for single-hand use, emphasizing ergonomic handling and ease of operation.

Battery Insertion and Removal: The battery pack is easily inserted into the base of the tool until it clicks into place. To remove, a release button is pressed, and the battery slides out. The battery packs feature an integrated fuel gauge, allowing users to check the remaining charge level at a glance by pressing a button. The LED indicators on the battery show charge levels ranging from 100% down to less than 10%.
Loading Fasteners: Fasteners are loaded into the magazine by pulling back the fastener pusher, inserting a strip of brad nails, and then releasing the pusher to secure them. The magazine is designed for quick and straightforward loading.
Power On/Off: The tool is switched on by pressing and holding the power button for 2 seconds. An LED indicator illuminates to confirm the tool is active.
Mode Selection: Users can switch between Single Sequential Actuation and Contact (Bump) Actuation by pressing the mode button. The corresponding LED (T or TIT) will light up to indicate the selected mode.
Low Battery Indication: A red LED on the tool illuminates when the battery is low, indicating that the tool will soon be unable to fire nails and requires recharging.
Clearing Jammed Fasteners: In the event of a fastener jam, the tool is designed for easy clearing. The user can open the nose of the tool to access and remove the jammed fastener. This process involves releasing a latch and pivoting the nosepiece open.
Portability: The tool includes a belt hook, allowing users to conveniently hang the nailer from their belt when not in immediate use, enhancing job site mobility.

Maintenance Features:

Regular maintenance is essential to ensure the longevity and optimal performance of the M18 FN18GS.

Battery Care: Battery packs should be recharged before use, especially if they have not been used for some time. It is recommended to avoid exposing batteries to temperatures above 50°C (122°F) and direct sunshine to prevent overheating and reduced performance. The contacts of both the charger and battery packs should be kept clean. For optimal battery life, the battery pack should be fully charged after use and removed from the charger once fully charged. For storage longer than 30 days, batteries should be stored in a cool, dry place (below 27°C) with a 30%-50% charge, and recharged every six months.
Ventilation Slots: The ventilation slots on the machine must be kept clear at all times to prevent overheating during operation.
General Inspection: Before each use, or if the tool has been dropped or subjected to a sharp blow, a daily test should be performed. This includes checking all screws, bolts, nuts, and pins for tightness, ensuring the workpiece contact moves smoothly, and verifying trigger functionality. The tool should also be tested in both actuation modes to ensure proper operation.
Accessory and Spare Parts: Users should only use Milwaukee accessories and genuine Milwaukee spare parts for any replacements. For components not described in the manual, users are advised to contact Milwaukee service agents.
