Product Description

Quick Overview

This 20V cordless grease gun is designed for vehicle servicing, agricultural machinery, construction equipment, industrial maintenance and general mechanical lubrication. It helps deliver grease to hard-to-reach grease fittings without the repeated hand pumping required by a manual grease gun.

The tool is supplied with two 20V/3.0Ah lithium-ion batteries and a 20V/0.6A corded charger, making it suitable for distributors offering a complete ready-to-use maintenance kit.

Standard coupler compatibility, typically supplied with a 1/8" NPT connection or equivalent

Two 20V/3.0Ah batteries included for battery rotation during extended maintenance work

Cordless design avoids the need for an air compressor or mains power cable

Color box packaging suitable for retail, distributor and e-commerce sales

Suitable for OEM branding, custom packaging and multilingual manuals according to order requirements

Solve the problem

1. Manual grease guns are slow and physically demanding

When servicing multiple grease points on trucks, agricultural machinery or construction equipment, repeated manual pumping takes time and causes hand fatigue. The 20V cordless drive system delivers grease automatically, helping maintenance teams complete lubrication work more efficiently.

2. Low-pressure grease guns cannot reach blocked or heavily loaded grease points

Grease fittings on excavators, loaders, tractors and industrial machinery can require considerable pressure, especially when grease is cold or the bearing passage is partially blocked. A typical high-pressure output of up to 10,000 PSI helps the operator work with demanding lubrication points.

3. Downtime caused by short operating time or frequent refilling

Outdoor maintenance often takes place away from workshops and fixed power sources. The standard kit includes two 20V/3.0Ah batteries, allowing one battery to be used while the other is charging or kept as a spare. The large grease barrel also reduces the frequency of refilling during routine service work.

FAQ

Q1: What type of grease can this cordless grease gun use?

The typical target range for this type of product is NLGI 0 to NLGI 2 grease. The actual grease compatibility depends on the pump, seals, follower system and operating temperature.

For bulk grease filling, the grease should be clean and free from hard particles. Contaminated grease can damage the pump or block the hose and coupler.

Q2: What does 10,000 PSI mean in practical use?

The pressure rating indicates the maximum pressure the tool may develop under restricted flow conditions. It helps the operator work with grease fittings that are difficult to fill or partially blocked.

Pressure and flow should not be considered separately. At maximum pressure, the actual grease delivery rate is normally lower than the free-flow rate.

Q3: Is 10,000 PSI the normal working pressure?

No. 10,000 PSI is typically a maximum pressure rating, not the pressure maintained during every lubrication task. Actual pressure depends on grease viscosity, fitting condition, hose resistance and bearing back pressure.

The final product manual should state the correct working pressure and maximum pressure separately.

Q4: How much grease can the barrel hold?

A common capacity for this class of cordless grease gun is approximately 400g / 14oz. The exact capacity should be confirmed based on whether the product uses a standard cartridge, bulk-fill tube or a transparent grease barrel.

Do not exceed the marked fill line, as overfilling can increase resistance and affect grease delivery.

Q5: Can it use standard grease cartridges?

This depends on the barrel design. Many cordless grease guns support standard cartridges, bulk filling or suction filling, but not every model supports all three methods.

Before publishing the product page, confirm:

• Cartridge size and length

• Cartridge diameter

• Bulk-fill capability

• Suction-fill capability

• Follower rod design

Q6: What is the purpose of the flexible hose?

The hose allows users to reach grease fittings located behind wheels, inside chassis structures, around suspension components or between machinery parts.

The operator should avoid sharply bending or twisting the hose under pressure, as this can damage the hose and restrict grease flow.

Q7: Is the included coupler suitable for all grease fittings?

The supplied coupler is generally designed for standard grease nipples, but fitting dimensions and locking mechanisms can vary between markets and equipment brands.

For professional fleet and machinery users, a replacement coupler or 90-degree adapter can be offered as an optional accessory.

Q8: Why does the grease flow rate vary?

Grease delivery depends on:

• Grease grade and viscosity

• Ambient temperature

• Battery charge level

• Hose length and condition

• Back pressure at the fitting

• Pump wear

• Air trapped in the grease barrel

A grease gun may deliver less grease in cold conditions or when using high-viscosity grease.

Q9: How can users prevent air locks in the grease barrel?

Users should load grease correctly, avoid introducing excessive air during bulk filling and follow the manufacturer’s venting instructions. Air in the pump chamber may cause inconsistent delivery or temporary loss of pressure.

A pressure relief or venting system is useful, but its availability must be confirmed for the actual product version.

Q10: Are the 20V/3.0Ah batteries compatible with other 20V tools?

Not necessarily. Battery compatibility depends on the mechanical interface, electrical terminals, protection board and battery management system, not voltage alone.

If this grease gun belongs to a wider 20V product platform, the battery interface should be standardized across all tools.

Q11: Is the 0.6A charger suitable for the 3.0Ah batteries?

The supplied 20V/0.6A charger is a basic charger for standard charging. The actual charging time depends on the battery protection circuit, battery temperature and remaining capacity.

For fleet maintenance and professional users, a faster charger may be offered as an optional accessory if it is validated for the battery pack.

Q12: What maintenance does the grease gun require?

After use, wipe excess grease from the barrel, hose and coupler. Check the hose and coupler regularly for leakage, cracks or damaged threads.

If grease flow becomes inconsistent, check for air in the barrel, blocked fittings, hardened grease or a clogged coupler before replacing pump components.

Q13: What spare parts should distributors stock?

Recommended service items include:

• High-pressure hose

• Locking grease coupler

• Grease barrel or cartridge tube

• Sealing rings

• Follower assembly

• Pressure relief valve

• Batteries

• Chargers

Maintaining a small stock of hoses and couplers can reduce downtime because these parts are exposed to pressure and regular handling.

Q14: Can this grease gun be used for industrial machinery?

Yes, it is suitable for routine lubrication of compatible grease points on industrial machinery, vehicles and construction equipment. However, the user must verify the required grease type, pressure and fitting compatibility for the specific machine.

It should not be connected to systems that exceed the confirmed pressure rating of the hose, coupler or grease gun.

Q15: What certifications are available?

Certification depends on the final design, battery pack, charger and target market. Common requirements may include CE, RoHS or UKCA. Confirm the available test reports and declarations before making compliance claims on the product page or packaging.
