Description
Yato cordless caulking gun 18V 4 Ah set includes a cordless caulking and adhesive gun, a 4 Ah Li-Ion battery and a charger. The gun uses motor power to dispense cartridges 48 mm in diameter and up to 255 mm long, with a volume of 300 ml , and the set is ready to use without buying a separate battery.
The steel plunger has a pressing force of 2000 N, and the plunger speed is adjusted steplessly with a rotary dial between 0.5–8 mm/s (30–480 mm/min). The speed is matched to the flowability of the compound: low speed for silicone and acrylic, higher speed for stiff construction adhesives and chemical anchors.
When the operating switch is released, the plunger stops and retracts slightly, which releases the pressure on the cartridge and prevents the compound from dripping. An end-position sensor stops the plunger automatically when the cartridge is empty. The battery has a charge level LED indicator, and the charger indicator lights show charging (red) and a fully charged battery (green).
Without the battery, the gun weighs 1.3 kg. The body and cartridge holder are made of metal. The operating voltage is 18 V DC, protection class III and IP rating IPX0, so the unit is intended for dry conditions. The sound pressure level is 81 dB(A) and the vibration value 1.76 m/s².
Uses and suitability:
The Yato cordless caulking gun 18V 4 Ah set is designed for applying cartridge compounds in construction, installation and maintenance work where there are many joints to seal or the compound is stiff.
- Sealing and caulking: Applying silicones, acrylic sealants, MS polymers and sealing compounds to window, door, bathroom and facade joints with an even, adjustable feed.
- Construction adhesives: Dispensing stiff installation and construction adhesives onto mouldings, panels and boards; the 2000 N pressing force is enough even for feeding cold, thick adhesive.
- Chemical anchors: Dispensing 300 ml chemical anchor compounds into drill holes in fixing and concrete work where the force of a manual gun is not enough.
- Vehicle and industrial maintenance: Applying adhesives and sealants in workshops and production, where repeated manual squeezing strains the wrist; the 4 Ah battery lasts through long work sessions.
The battery and charger in the set belong to the Yato 18 V battery system and also fit other tools in the range, such as Yato cordless grease gun 18V 620 bar body only and Yato cordless drill 18V 45Nm, brushless motor, body only. A suitable extra battery is the Yato 18V Li-Ion battery. The gun body alone, without a battery, is available under code YT-82889.

Features:
- Ready-to-use set: 4 Ah battery and charger included; one charge is enough to dispense several cartridges.
- Variable speed control: The rotary dial sets the plunger speed at 0.5–8 mm/s, so the feed suits both fluid and stiff compounds.
- Automatic plunger retraction: Releasing the switch pulls the plunger back and prevents the compound from dripping and smearing surfaces.
- End-position sensor: Stops the plunger when the cartridge empties, which protects the mechanism from overload.
- Plunger release button: The plunger is pulled back by hand and pushed against the cartridge piston without tools.
- Metal cartridge holder and steel plunger: Withstand a pressing force of 2000 N even with stiff compounds.
- Battery charge level display: LED indicators show the remaining charge at the press of a button.
- Yato 18 V battery system: The same battery and charger fit the other tools in the range; spare batteries 2 Ah, 3 Ah, 4 Ah and 6 Ah.

Yato cordless caulking gun 18V 4 Ah user manual:
Charging: Wipe the battery contacts with a dry cloth, insert the battery into the charger and plug the charger into a socket. The red LED is lit while charging and the green LED indicates a fully charged battery. Unplug the charger and release the battery from the charger with the latch button. The battery is supplied uncharged.
Fitting the cartridge: Remove the battery. Open the cartridge nozzle according to the manufacturer’s instructions before fitting; a closed cartridge can damage the gun or force compound out on the piston side. Press the plunger release button and pull the plunger back by hand. Place the cartridge first in the front of the holder and then press the rear into the holder. With the release button pressed, push the plunger against the cartridge piston.
Use: Check that the operating switch is not pressed, and attach the battery. Grip the gun with both hands, aim the nozzle at the joint and press the switch. Find the right plunger speed with the rotary dial by trial; keep the nozzle close to the surface and move it with an even motion. Releasing the switch stops the feed and pulls the plunger back slightly.
Blockage: If no compound comes out and the gun runs heavily or vibrates, release the switch immediately, remove the battery and check the nozzle opening and any hardened compound.
Maintenance and battery: Remove the battery before cleaning. Remove any compound from the gun before it hardens, without using solvents, acids or abrasives. Clean the housing and ventilation openings with compressed air (max. 0.3 MPa), a brush or a dry cloth. Store the battery at 0–30 °C at about 70% charge and recharge it once a year during long-term storage. Do not dismantle the device during the warranty period.
Warnings:
- Read the instruction manual and the safety data sheet of the compound being applied before starting work; wear the personal protective equipment the compound requires.
- Never point the cartridge nozzle at people or animals or place it on the skin: the compound is forced out with great force and can penetrate under the skin.
- Do not put your fingers between the plunger and the cartridge holder; the 2000 N pressing force can cause serious injury.
- Always remove the battery before changing the cartridge, making adjustments and cleaning.
- Use only cartridges whose dimensions match the technical data; do not modify the gun for other cartridges.
- Charge the battery only with the supplied charger, in a dry place and under supervision; do not use a damaged charger or battery. Do not short-circuit the battery terminals.
- Wear safety glasses and ear defenders; do not use the gun in rain or wet conditions (IPX0).
