  • Page 4: Product Name

    Model H 60MRV 2. MARKETING OBJECTIVE The Models H 60MR and H 60MRV are upgraded versions of the current Models H 60MA and H 60MB which feature the use of maker B's SDS-max shank tools. The performance, durability and operability are greatly improved.

  • Page 5: Selling Point Descriptions

    Thus the housing has greater rigidity and the double-insulated motor has greater durability. The Models H 60MR and H 60MRV are heavy-duty and the service life of the carbon brushes is prolonged, minimizing disconnection of the armature, deviation of the core and grease leakage.

    4-1-8. Original design vibration-absorbing handle (Vibration-absorbing is significantly improved) Hitachi's original design vibration-absorbing handle minimizes vibration through the rolling and compression of four cylindrical rubber cushions on inclined surfaces. The spring constant factor is as low as that of the Models H 41SC, H 45MR, H 45SR, H 45FRV and H 60KA, and the cushioning structure greatly reduces vibration.

    7. PRECAUTIONS IN SALES PROMOTION In the interest of promoting the safest and most efficient use of the Models H 60MR and H 60MRV Demolition Hammers by all of our customers, it is very important that at the time of sale the salesperson carefully ensures that the buyer seriously recognizes the importance of the contents of the Handling Instructions, and fully understands the meaning of the precautions listed on the Caution Plate attached to each tool.

  • Page 12: O-Ring Replacement

    7-4. O-ring Replacement The O-ring (mounted on the striker and piston) are extremely important to ensure adequate sealing of the air pressure. Although the O-rings are made of special rubber to give them a long service life, they do nonetheless become worn, and should be replaced by new ones periodically depending on frequency of use of the tool.

  • Page 13: Idling-Proof Mechanism

    (damper (C)) provided between the retainer sleeve and the front cover absorbs the striking force of the tool when it pops up. Thus the durability of the Models H 60MR and H 60MRV is increased greatly because the tool and the second hammer do not strike the tool retainer directly.

  • Page 14: Sealed And Dustproof Construction

    8-5. Vibration Absorbing Construction Hitachi original, innovative units which absorb vibration are installed between the switch handle and the crank case and between the switch handle and the housing. As a result, the amount of vibration transmitted from the main body to the arms of the operator is considerably less in comparison with conventional hammers.
