Overview

This document provides an instruction manual for the Makita Cordless Grass Trimmer, models DUR187U, DUR187L, DUR188U, and DUR188L. It covers safety warnings, functional descriptions, assembly, operation, and maintenance.

Function Description

The Makita Cordless Grass Trimmer is designed for cutting grass and light weeds. It operates on a D.C. 18V battery and features a motor that drives either a nylon cutting head or a plastic blade. The tool is equipped with a tool/battery protection system that automatically cuts off power to the motor under certain conditions to extend tool and battery life. These conditions include overload, overheating (of the tool or battery), and overdischarge (low battery capacity). The trimmer also includes a reverse rotation function, primarily for removing entangled weeds or debris from the cutting head.

Usage Features

The trimmer offers several user-friendly features:

  • Battery Installation/Removal: Battery cartridges are easily installed by aligning the tongue with the housing groove and pushing until it clicks, and removed by sliding a button on the front of the cartridge. Users are cautioned to ensure the cartridge is fully locked and not to force it.
  • Power Switch Action: The tool is turned on by pressing and holding the main power button for a few seconds, and turned off by pressing and holding it again. A lock-off lever is provided to prevent accidental pulling of the switch trigger. To start the tool, the handle must be grasped (releasing the lock-off lever) and the switch trigger pulled.
  • Speed Adjustment: The tool speed can be adjusted by tapping the main power button, cycling through different speed levels.
  • Reverse Button for Debris Removal: A dedicated reverse button allows for temporary reverse rotation of the cutting head. This feature is specifically for removing entangled weeds or debris and operates for a short period before automatically stopping.
  • Handle/Hanger Adjustment: The handle and hanger positions can be adjusted to achieve a comfortable working position, enhancing user comfort and control. This involves loosening hex socket head bolts, repositioning, and then tightening the bolts.
  • Shoulder Harness: The tool comes with a shoulder harness for comfortable operation and to prevent fatigue. It is crucial to adjust the harness according to user size and ensure the tool is securely held.
  • Guard Installation: A guard must always be installed to prevent personal injury. The guard's projections align with grooves in the motor housing and are secured with hex socket head bolts.
  • Wire Guard: A wire guard can be installed to control the cutting range and reduce the risk of damaging objects in front of the cutting head. It is inserted into holes in the protector after being slightly expanded.
  • Cutting Tools: The trimmer supports both nylon cutting heads and plastic blades. The nylon cutting head features a bump & feed mechanism to feed out the nylon cord by tapping it against the ground while rotating.

Maintenance Features

Regular maintenance is crucial for the tool's safety and longevity:

  • Pre-Maintenance Safety: Before any inspection or maintenance, the tool must be switched off, and the battery cartridge removed to prevent accidental start-up and serious personal injury.
  • Cleaning: The tool should be kept clean, and ventilation openings clear of debris. Handles should be kept dry, clean, and free from oil and grease.
  • Cutting Tool Inspection: The cutting tool, protective devices, and shoulder strap must be checked regularly for wear or damage. If the nylon cutting head or plastic blade impacts a hard object, the tool should be stopped immediately, inspected for damage, and replaced if necessary.
  • Nylon Cord Replacement: The manual provides detailed instructions for replacing the nylon cord, including preparing a specific length of new cord and winding it correctly onto the spool.
  • Plastic Blade Replacement: Instructions are given for replacing the plastic blade, emphasizing proper alignment with the protector's arrow.
  • Battery Cartridge Care: To maintain maximum battery life, the cartridge should be charged before it is completely discharged, not overcharged, charged at room temperature, and charged if not used for a long period (over six months).
  • Hex Wrench Storage: The hex wrench should be stored in its designated slot on the tool to prevent loss and avoid injury or damage.
  • Troubleshooting: A troubleshooting guide is provided to help users identify and remedy common issues such as the motor not running, the motor stopping after short use, failure to reach maximum RPM, the cutting tool not rotating, abnormal vibration, or the cutting tool and motor not stopping. For issues not covered or if repairs are needed, users are advised to contact a Makita Authorized Service Center.
  • Genuine Parts: Users are strongly advised to use only genuine Makita batteries, chargers, and replacement parts to ensure product safety, reliability, and to avoid voiding the warranty. The use of non-genuine parts or metal blades is explicitly warned against due to potential risks of fire, personal injury, and damage.
