This document is the Instruction & User Manual for the JCB 21-DH1700 Power Tool, a corded demolition hammer.

Function Description

The JCB 21-DH1700 is a power tool specifically designed for chiselling in stone, brick, and concrete. It operates as a demolition hammer, utilizing a percussion chiselling mechanism to break down tough materials. The tool is intended for heavy-duty applications where significant impact force is required for demolition tasks.

Important Technical Specifications

• Model Designation: 21-DH1700 (DH - Demolition Hammer, 1700 - 1700W power)
• Input Voltage: 230-240V~, 50Hz
• Power: 1700W
• Hammer Impact Rate: 2000bpm (blows per minute)
• Protection Class: II (Double insulated, meaning an earth wire is not fitted)
• Impact Energy: 65J (Joules)
• Net Weight: 16.4kg
• Chuck Type: 30MM HEX CHUCK attachment system
• Noise Information (determined according to EN 60745-1 and EN 60745-2-6):
  • A-Weighted Sound Pressure (LPA): 93.2dB(A)
  • A-Weighted Sound Level (LWA): 104.6dB(A)
  • Uncertainty (KWA): 3 dB(A)
  • Users are advised to wear ear protection when sound pressure exceeds 80 dB(A).
• Vibration Information (triax vector sum determined according to EN 67045-1 and EN 60745-2-6):
  • Chiselling (ah, Cheq): 21.34 m/s²
  • Uncertainty (K): 1.5 m/s²
  • The manual warns that this tool may cause Hand-Arm Vibration Syndrome if usage is not adequately managed. It recommends minimizing exposure, using sharp and undamaged bits, maintaining the tool, investing in anti-vibration accessories for regular use, avoiding use in temperatures below 10°C, and planning work schedules to spread high vibration tool use.

Usage Features

• Safety Warnings: The manual emphasizes reading all safety warnings, instructions, and specifications to reduce the risk of injury. It highlights the importance of personal protective equipment (PPE) such as ear defenders, eye protection, safety gloves, and a dust mask.
• Work Area Safety: Users are instructed to keep the work area clean and well-lit, avoid operating in explosive atmospheres, and keep children and bystanders away.
• Electrical Safety: Power tool plugs must match outlets, and adapter plugs should not be used with earthed power tools. Users should avoid body contact with earthed surfaces, exposure to rain or wet conditions, and abusing the power cord. For outdoor use, an appropriate extension cord is required, and a residual current device (RCD) is recommended for damp locations.
• Personal Safety: Users must stay alert, use common sense, and not operate the tool while tired or under the influence of drugs, alcohol, or medication. Preventing unintentional starting by ensuring the switch is off before connecting to power or carrying the tool is crucial.
• Tool Handling: The tool should be held by insulated gripping surfaces, especially when there's a risk of contacting hidden wiring. An auxiliary handle (3) is supplied and its use is recommended at all times for better control and to prevent personal injury.
• Bit Changing: The device features a 30mm HEX attachment system. To insert a bit, clean and grease it, then push it into the chuck as far as possible. Pull out the locking bolt (a), turn it 180°, and release to lock the chisel. To remove, pull out the locking bolt (a) again, turn it 180°, and remove the chisel.
• Auxiliary Handle Adjustment: The auxiliary handle (3) can be loosened by turning anti-clockwise, rotated to the desired working position, and then re-tightened firmly.
• Initial Operation: Before drilling in blind areas, users must use appropriate detectors to locate hidden electric, gas, or water lines to prevent serious injury or property damage.
• On/Off Trigger (2A): Pressing the trigger starts the tool, and releasing it stops the tool.
• Constant Speed (Lock-On Button 2B): To activate constant speed, gradually squeeze the ON/OFF trigger (2A) until fully retracted, then press the locking button (2B). Release pressure on the trigger, and the tool will operate at a constant speed. To release the lock, apply pressure to the ON/OFF trigger, which will automatically release the locking button, and then release the trigger to stop the tool.
• Electromagnetic Field Warning: The tool generates an electromagnetic field that may interfere with active or passive medical implants. Users with medical implants are advised to consult their physician and implant manufacturer before operating.

Maintenance Features

• General Maintenance: Before any cleaning or maintenance, the tool must be switched off and disconnected from the power supply to prevent electric shock and accidental starting.
• Cleaning: The tool should be wiped with a dry or damp cloth. Wet cloths, detergents containing solvents, corrosive, or abrasive additives should not be used as they can damage the surface.
• Ventilation: Keep ventilation openings open to prevent overheating. Clear tool vents and the SDS Hex® Chuck of dust and dirt after each use. Avoid inserting sharp objects into ventilation holes. Stubborn contamination can be removed with compressed air (max 3 bar).
• Fasteners: Regularly check all fasteners, screws, and bolts to ensure they are tight. Loose screws should be tightened immediately to prevent serious injury.
• Cord Replacement: If the power cord is damaged, it must be replaced by the manufacturer or an authorised JCB Service Centre.
• Internal Parts: The manual explicitly states that the tool should never be opened by the user as it has no internal parts that can be serviced or repaired by the user. Any repairs must be performed by an authorised service centre.
• Carbon Brushes: If carbon brushes require replacement, this must be performed by an authorised warranty agent.
• Post-Use Inspection: After use, inspect the tool to ensure it is in top condition. It is recommended to take the tool to an Authorised Service Centre for thorough cleaning and re-lubrication at least once a year.

Transport and Storage

• Weight: The power tool is heavy, and users are cautioned to transport and operate it with care.
• Long-Term Storage: If unused for an extended period, the tool should be stored in its original packaging.
• Storage Conditions: Store the tool in a dry, frost-free, well-ventilated place with a temperature not exceeding 40°C and out of reach of children.
• Protection: Protect the tool from direct sunlight.
• Transport Safety: Always switch off the tool and disconnect it from the power supply before transport. Carry the tool using its purpose-designed handle. Ensure the tool is not at risk of tipping over or exposed to vibration and shocks during transport, especially when transported by car or other vehicle.
