Craftsman CMCGG001 Cordless Grease Gun Kit Manual

Introduction

The craftsman CMCGG001 Cordless Grease Gun Kit is a portable 20V MAX cordless lubrication tool designed for maintaining vehicles, agricultural machinery, construction equipment, trailers, and industrial machinery. Its battery-powered design eliminates the need for an air compressor or electrical outlet, making it practical for workshops, garages, job sites, and field service.

This V20 grease gun uses a two-speed transmission to match output to the application. Speed 1 delivers up to 10,000 PSI for working through clogged or resistant grease fittings, while Speed 2 provides higher flow for routine lubrication. The variable-speed trigger helps control grease delivery and reduces waste when servicing smaller fittings or sensitive components.

A 40-inch flexible hose helps reach fittings positioned behind wheels, under machinery, and around suspension components. The integrated LED work light can improve visibility in dim service areas. The kit version typically includes the CMCGG001 grease gun, one 2.0Ah battery, a charger, and a storage bag.

This cordless grease gun suits mechanics, fleet operators, farmers, maintenance technicians, and serious DIY users who regularly lubricate equipment. It is especially useful when multiple grease points must be serviced away from a workshop. Before use, confirm the grease specification required by the equipment manufacturer and follow all safety instructions in the tool manual.

Wear eye protection and gloves. Never place hands near the coupler while the tool is operating, and never exceed the pressure rating of the fitting or component being serviced.

Craftsman CMCGG001 Troubleshooting Guide

Grease does not flow: Confirm that the battery is charged, the barrel contains grease, and the tool is switched on. Release trapped air and check that the hose is not kinked.
The pump runs but delivery is weak: Inspect the coupler for poor engagement, clean the fitting, and try Speed 1. A blocked fitting may require cleaning or replacement rather than additional pressure.
Grease leaks around the barrel: Stop the tool, remove the battery, and inspect the barrel seal, follower, and cartridge installation. Replace damaged seals or reload the barrel correctly.
The battery will not charge: Check that the battery is fully seated in the charger and that the charger is connected to a working outlet. Allow an overheated battery to cool before charging.
The LED does not illuminate: Remove and reinstall the battery. If the light remains inoperative while the tool functions, discontinue use if other electrical symptoms appear and request service.
No specific display error codes: The CMCGG001 is not described as having a user-facing digital error-code display. Treat abnormal shutdown, overheating, or unusual noise as a reason to stop and inspect the tool.

Prevent problems by wiping fittings before lubrication, using clean compatible grease, keeping the hose protected from sharp edges, and removing the battery before maintenance.

Pros and Cons of the Craftsman CMCGG001 Grease Gun

Advantages

Cordless portability: The V20 battery system is convenient for field repairs and equipment located away from power outlets or compressors.
Two operating speeds: High pressure helps address resistant fittings, while the higher-flow setting speeds up regular maintenance.
Controlled application: The variable-speed trigger makes it easier to dispense grease gradually and avoid over-lubrication.
Extended reach: The 40-inch hose is useful for fittings behind guards, wheels, axles, and other confined areas.
Work light: The LED can improve visibility during indoor, underbody, or low-light servicing.
System compatibility: Existing CRAFTSMAN V20 battery owners may be able to share batteries across compatible tools.

Limitations

Battery runtime depends on workload: Frequent high-pressure pumping or heavy grease use can reduce runtime more quickly than occasional lubrication.
Manual loading is required: Like most professional grease guns, correct cartridge installation and air removal are essential for dependable pumping.
Limited by fitting condition: A severely blocked or damaged grease fitting may not accept grease even when the tool is operating correctly.
Bulkier than a manual grease gun: Users needing a compact emergency tool for infrequent lubrication may prefer a simpler hand-operated model.

The Craftsman CMCGG001 Cordless Grease Gun Kit is best suited to users who perform repeated maintenance and value cordless reach, pressure, and speed. A manual grease gun may be more appropriate for occasional light-duty use or when battery tools are not needed.

Faqs

How do I set up the Craftsman CMCGG001 Cordless Grease Gun Kit for the first time?

Charge the included V20 battery, then install it firmly into the grease gun until it clicks. Attach the 40-inch flexible hose securely to the pump outlet and connect the coupler to the grease fitting. Load a compatible grease cartridge or bulk grease according to the manual, checking that seals are seated correctly. Before lubricating equipment, briefly run the tool with the coupler disconnected to remove trapped air and confirm that grease flows normally.

What type of grease can I use in the Craftsman CMCGG001 Cordless Grease Gun Kit?

The Craftsman CMCGG001 Cordless Grease Gun Kit is designed for grease up to NLGI #2 consistency. Use the lubricant specified by the equipment manufacturer, because mixing incompatible greases can cause separation, hardening, or poor lubrication. Keep the cartridge, bulk grease, hose, and coupler clean during loading. Never force an unusually thick, contaminated, or frozen lubricant through the tool, since it can restrict flow and increase the risk of pump or hose problems.

Why is the Craftsman CMCGG001 Cordless Grease Gun Kit running but not dispensing grease?

If the motor runs without pumping grease, check for an empty cartridge, an improperly seated plunger, or air pockets in the lubricant. Inspect the hose and coupler for blockage, then release pressure before disconnecting fittings. If the grease gun has lost its prime, operate it briefly with the coupler disconnected while gently loosening the air-release mechanism if equipped. Reload the grease carefully and do not continue operating the tool if the hose is damaged.

How do I remove air pockets from the Craftsman CMCGG001 grease gun?

Air pockets can interrupt grease flow and make the Craftsman CMCGG001 Cordless Grease Gun Kit lose its prime. First remove the battery and relieve pressure safely. Check that the cartridge or bulk grease is installed evenly and that the follower rod is engaged correctly. Reinstall the battery, point the hose away from people, and run the gun briefly with the coupler disconnected. Stop once a steady stream of grease appears, then reconnect the coupler.

When should I use speed 1 or speed 2 on the Craftsman CMCGG001 Cordless Grease Gun Kit?

Use speed 1 when a grease fitting is clogged or requires higher pressure; this setting delivers up to 10,000 PSI with a slower flow rate. Choose speed 2 for high-flow lubrication jobs where the fitting accepts grease easily and faster delivery is useful. The variable-speed trigger lets you fine-tune output in either application. Start slowly to avoid over-greasing seals, damaging fittings, or forcing lubricant past worn components.

Which batteries and chargers are compatible with the Craftsman CMCGG001 grease gun?

The Craftsman CMCGG001 Cordless Grease Gun Kit uses the CRAFTSMAN V20 battery system. The kit version includes a 2.0 Ah battery and charger, while tool-only packages may not include either accessory. Use a compatible V20 lithium-ion battery and the appropriate CRAFTSMAN charger rather than attempting to adapt another voltage platform. Inspect battery contacts before installation, and remove the battery whenever you transport, clean, load, or service the grease gun.

How can I improve grease flow when using the Craftsman CMCGG001 Cordless Grease Gun Kit?

For better performance, use clean grease of the correct consistency and keep the hose as straight as practical. Fully charge the V20 battery, select speed 2 for unrestricted high-flow work, and use the variable-speed trigger instead of immediately holding it fully open. If flow remains weak, inspect the fitting for blockage and check for air in the barrel. Do not exceed the tool’s intended grease specification or continue against a severely obstructed fitting.

How should I clean and store the Craftsman CMCGG001 Cordless Grease Gun Kit?

Remove the battery before cleaning or storing the Craftsman CMCGG001 Cordless Grease Gun Kit. Wipe grease from the housing, hose, coupler, and fittings with a clean cloth, preventing dirt from entering the pump or cartridge opening. Relieve internal pressure after use and inspect the flexible hose for cuts, swelling, or leaks. Store the tool in its bag in a dry location, protect the battery from extreme temperatures, and recharge it using the approved charger.
