Safety Instructions

General Safety Warnings:

• Read all safety warnings and instructions. Failure to follow warnings and instructions may result in electric shock, fire, and/or serious injury.
• Save all warnings and instructions for future reference.

Specific Safety Instructions:

• High pressure can cause tool parts or hose assembly to rupture, posing a risk of injection injury and/or amputation. Inspect tool and hose assembly for damage or wear before each use. Do not use if damaged or worn.
• Hold hose assembly by spring strain relief to avoid kinking the hose.
• Grease and lubricants may be flammable. Do not expose to flame or heat source. Follow all warnings and instructions from grease and lubricant manufacturer.
• To avoid damage to the grease gun and pump, the loader fitting must be compatible with the coupler and rated for at least 690 bar.
• Always wear goggles when using the machine. It is recommended to wear gloves, sturdy non-slipping shoes, and an apron.
• Remove the battery pack before starting any work on the machine.
• Do not dispose of used battery packs in household refuse or by burning them. Milwaukee Distributors offer to retrieve old batteries to protect our environment.
• Do not store the battery pack together with metal objects (short circuit risk).
• Use only System M18 chargers for charging System M18 battery packs. Do not use battery packs from other systems.
• Battery acid may leak from damaged batteries under extreme load or extreme temperatures. In case of contact with battery acid, wash it off immediately with soap and water. In case of eye contact, rinse thoroughly for at least 10 minutes and immediately seek medical attention.
• Warning! To reduce the risk of fire, personal injury, and product damage due to a short circuit, never immerse your tool, battery pack or charger in fluid or allow a fluid to flow inside them. Corrosive or conductive fluids, such as seawater, certain industrial chemicals, and bleach or bleach containing products, etc., can cause a short circuit.

Operation

Priming the Grease Gun:

1. Hold the hose assembly by the spring strain relief and point away from your body.
2. Pull the trigger for 3 seconds, release, and repeat until grease begins to flow from the fitting.
3. If after several attempts grease does not appear, manually prime the grease gun:
• Pull back the rod and turn the rod handle to lock into the plunger.
• Press in the bleed valve while manually pressing in the rod.
• Once grease begins to flow from the fitting, rotate the rod handle to release the plunger. Press the rod completely into the cylinder.

Note: This tool has been tested to factory standards, which results in a small amount of grease being left in the pump body, hose and coupler assembly. It is recommended that you purge this tool with the brand of grease you will be using before actual use.

Troubleshooting

• Unable to pull back rod: Press the bleeder to release pressure.
• Unable to push rod forward: Rotate rod 90° to disengage it from plunger.
• No grease when trigger is pulled: Cylinder is empty, add grease. Air pockets in the cylinder, prime the grease gun.

• Temperatures in excess of 50°C (122°F) reduce the performance of the battery pack. Avoid extended exposure to heat or sunshine (risk of overheating).
• The contacts of chargers and battery packs must be kept clean.
• For an optimum life-time, the battery packs have to be fully charged, after used.
• To obtain the longest possible battery life remove the battery pack from the charger once it is fully charged.
• For battery pack storage longer than 30 days: Store the battery pack where the temperature is below 27°C and away from moisture. Store the battery packs in a 30% - 50% charged condition. Every six months of storage, charge the pack as normal.

Battery Pack Protection Li-Ion Battery

The battery pack has overload protection that protects it from being overloaded and helps to ensure long life. Under extreme stress the battery electronics switch off the machine automatically. To restart, switch the machine off and then on again. If the machine does not start up again, the battery pack may have discharged completely. In this case it must be recharged in the battery charger.
