MAINTENANCE

ENGINE OIL

Perform engine maintenance with the engine off, spark plug wires disconnected and PTO disengaged.

AFTER FIRST FIVE (5) HOURS

While the engine is warm:

1.Remove drain cap at location D and drain the crankcase. Dispose of used oil in accordance with local requirements.

2.Clean and replace the cap.

3.Change oil filter.

4.Fill the crankcase with fresh oil to the full mark. Do not overfill. See engine manual for oil specifications.

DAILY

1.Check oil level with the dipstick.

2.If oil is needed, add fresh oil of proper

viscosity and grade. See engine manual for oil specifications. Do not overfill.

3.Replace dipstick before starting engine.

PERIODIC OIL CHANGES

1.See Page 22 maintenance chart for oil and filter change intervals after the break-in period.

2.Follow instructions for first oil change, above.

OIL CAPACITY

Engine without oil filter holds approximately 1-7/8 quarts (60 ounces; 1.8 liters).

Engine equipped with oil filter holds approximately 2 quarts (64 ounces; 1.9 liters).

Use a high quality detergent oil classifed "For Service SF, SG, SH, SJ" or higher.

Use recommended SAE viscosity grade oil per start- ing temperature according to Figure 1.

SPARK PLUGS

Remove each plug and check condition.

-Good operating conditions are indicated if the plug has a light coating of grey or tan deposit.

-A white blistered coating indicates overheating. A black coating indicates an "over rich" fuel mixture. Both may be caused by a clogged air cleaner or improper carburetor adjustment.

-Do not sandblast, wire brush or otherwise attempt to repair a plug in poor condition. Best results are obtained with a new plug.

-Set plug gap as specified in engine manual..

127.28876, 127.28877 specifications

The Craftsman 127.28877 and 127.28876 are a pair of high-performance cordless drills designed for both professional tradespeople and DIY enthusiasts. These models exemplify the blend of power, versatility, and user-friendly design that Craftsman tools are known for.

One of the standout features of both models is their brushless motor technology. This innovation enhances efficiency, delivering more power and runtime than traditional brushed motors. It also reduces heat generation, leading to prolonged tool life. With a high-torque output, these drills can easily handle demanding applications, making them ideal for tasks such as drilling into wood, metal, and masonry.

Both models come equipped with a two-speed transmission. This feature allows users to select the optimal speed based on the specific task at hand—whether it’s high-speed drilling for smaller holes or low-speed drilling for driving larger fasteners. The variable speed trigger further provides enhanced control, enabling a precise and seamless drilling experience.

The design of the Craftsman 127.28877 and 127.28876 is ergonomic, featuring a soft-grip handle that minimizes hand fatigue during extended use. The compact and lightweight structure allows for easy maneuverability in tight spaces, making it suitable for various job sites.

Another notable characteristic is the LED work light integrated into the drills, providing illumination in dimly lit areas. This feature ensures that users can work effectively without needing to reposition other lighting sources.

Battery compatibility is another key advantage of these models. Both drills utilize the Craftsman 20V MAX battery platform, allowing users to interchange batteries between different tools within the same line. This feature not only enhances convenience but also maximizes productivity by reducing downtime due to battery changes.

Finally, the construction of the Craftsman drills includes rugged materials that resist wear and tear, assuring durability over years of use. With a combination of advanced technology, user-centered design, and robust performance, the Craftsman 127.28877 and 127.28876 are invaluable additions to any tool collection, providing reliability and efficiency for a range of projects.
