Overview

This document provides the instruction manual for the Makita M8600 Demolition Hammer, a double-insulated power tool designed for chiselling work in concrete, brick, stone, and asphalt, as well as for driving and compacting with appropriate accessories. It emphasizes safety warnings, functional descriptions, and maintenance procedures to ensure safe and effective operation.

Function Description

The Makita M8600 Demolition Hammer is a robust tool intended for heavy-duty chiselling and demolition tasks. Its primary function is to deliver powerful blows to break down tough materials like concrete and stone. The tool is designed for continuous operation, offering ease of use for extended periods.

The operation of the demolition hammer is controlled by a switch trigger. To start the tool, the user simply pulls the switch trigger. Releasing the switch trigger stops the tool. For continuous operation, the switch trigger can be pulled and then locked into the "ON" position using the lock button. To stop the tool from the locked position, the switch trigger must be pulled fully and then released. This switch action allows for sustained work without constant pressure on the trigger, enhancing operator comfort during prolonged use.

The tool's design incorporates a side grip, also referred to as an auxiliary handle, which can be adjusted to various positions. This feature allows for easy handling of the tool in different orientations and working conditions, providing better control and reducing operator fatigue. The side grip can be loosened by turning it counterclockwise, swung to the desired position, and then tightened by turning clockwise to secure it.

The demolition hammer utilizes a bit for its chiselling and demolition functions. The bit is installed into a tool holder. Before installation, it is recommended to coat the bit shank head with a small amount of bit grease to ensure smooth action and prolong service life. To install the bit, the change ring on the tool holder is pulled down, and the bit is inserted as far as it will go. Releasing the change ring automatically secures the bit in its original position. Users are advised to always verify that the bit is securely held by attempting to pull it out. To remove the bit, the change ring is pulled down all the way, and the bit is pulled out.

When performing chiselling, scaling, or demolition, the tool should be held firmly with both hands. It is important to apply slight pressure to the tool to prevent it from bouncing uncontrollably. Pressing too hard will not increase efficiency and may lead to loss of control. The tool is designed to produce vibration during normal operation, and users should be aware that screws may come loose over time, necessitating regular checks for tightness to prevent breakdowns or accidents.

Usage Features

The M8600 Demolition Hammer is designed with several features to enhance user safety and operational efficiency.

  • Double Insulation: The tool is double-insulated, meaning it has two layers of insulating material between live parts and the user, providing an extra layer of protection against electric shock. This allows the tool to be used from sockets without an earth wire.
  • Adjustable Side Grip: The auxiliary handle can be swung around to either side, allowing the user to find the most comfortable and effective grip for various working positions. This flexibility improves control and reduces strain during operation.
  • Secure Bit Installation: The tool features a robust bit installation mechanism that ensures the bit is securely held in place, preventing accidental dislodgement during heavy-duty tasks. The recommendation to grease the bit shank before installation contributes to smoother operation and extended tool life.
  • Continuous Operation Lock: The switch trigger can be locked in the "ON" position, which is particularly useful for extended periods of work, reducing the need for constant finger pressure on the trigger and enhancing operator comfort. However, users are cautioned to maintain a firm grasp on the tool when the lock is engaged.
  • Vibration Management: While the tool inherently produces vibration, users are advised to be mindful of this and regularly check the tightness of screws to ensure the tool's integrity and prevent accidents.
  • Cold Weather Operation: In cold weather or after long periods of disuse, it is recommended to operate the tool under no load for a while to warm up the lubrication. This ensures proper functioning and prevents difficulties in hammering operations.
  • Material Compatibility: The tool is versatile, suitable for chiselling in concrete, brick, stone, and asphalt, making it a valuable asset for various construction and demolition projects.

Maintenance Features

Proper maintenance is crucial for ensuring the safety, reliability, and longevity of the Makita M8600 Demolition Hammer.

  • Pre-Maintenance Safety: Before performing any inspection or maintenance, it is imperative to ensure that the tool is switched off and unplugged from the power source. This prevents accidental startup and potential injury.
  • Cleaning and Lubrication: The bit shank should be coated with a small amount of bit grease before installation to ensure smooth action and extend the service life of the tool.
  • Avoidance of Harmful Substances: Users are strictly warned against using gasoline, benzine, thinner, alcohol, or similar substances for cleaning, as these can cause discoloration, deformation, or cracks in the tool's components.
  • Carbon Brush Replacement: The tool is equipped with carbon brushes that are designed to automatically shut off the motor when the resin insulating tip inside the brush is exposed to the commutator. When this occurs, both carbon brushes must be replaced simultaneously. It is important to use only identical carbon brushes and to keep them clean and free to slip in their holders. The replacement process involves removing the rear cover with a screwdriver, then using a screwdriver to remove the brush holder caps, taking out the worn brushes, inserting new ones, and securing the caps.
  • Screw Tightness Checks: Due to the tool's vibratory nature, screws can come loose. Regular checks for screw tightness are essential to prevent breakdowns and accidents.
  • Professional Servicing: For all other maintenance, adjustments, or repairs, it is strongly recommended to have the tool serviced by Makita Authorized Service Centers. These centers use only identical Makita replacement parts, which is vital for maintaining the product's safety and reliability.
  • Handle Maintenance: The handles should be kept dry, clean, and free from oil and grease to ensure a secure grip and prevent accidents.
  • Dust Management: If the tool is equipped with dust extraction and collection facilities, users must ensure these are properly connected and used to reduce dust-related hazards.
  • Storage: When not in use, the power tool should be stored out of the reach of children and individuals unfamiliar with its operation or the instructions.

By adhering to these maintenance guidelines, users can significantly extend the lifespan of their Makita M8600 Demolition Hammer and ensure its continued safe and efficient operation.
