Description

Rotary Hammers 26mm (1")

CONCEPT AND MAIN APPLICATIONS

HR2600/ HR2601 are 26mm (1") 2-mode rotary hammers adapted for SDS-PLUS bits, featuring compact and lightweight design, enhanced comfort and better control with ergonomic handle. Model HR2601 is equipped with AVT; Anti Vibration Technology consisting of Active dynamic vibration absorber with counterweight and Damper spring. AVT ensures operation with extremely low vibration, which is much superior to the competitors. HR2600 series models are available in the variations listed below, including HR2300 and HR2610 series models developed on the same concept.

REPLACING

(1) Remove three 4x18 Tapping screws and Handle cover. (2) Slide Brush holder unit to the best position to repair, and move the arms of Spiral springs aside, then separate Carbon brushes from Commutator. (Fig. 9) (3) Remove four 4x30 Tapping screws then separate Motor housing from Gear housing complete. Armature is left on Gear housing at that time. (Fig. 10) Note: Do not lose Wave washer 15 on the bottom of Motor housing. Do not fail to set it in place when assembling. (4) Remove Armature ass’y from Gear housing complete by pulling by hand. Note: Ball bearing 6000LLB of Armature ass’y is held in Inner housing complete with O ring 26. Therefore, it is not necessary to tap Gear housing complete with Plastic hammer to remove Armature ass’y. (5) Remove Ball bearings 6000LLB with 1R269. Remove 627DDW and Insulation washer together at one time with 1R269. (6) Assemble the components in the reverse order of disassembly after replacing the damaged parts.

DISASSEMBLING

(1) Put 1R388 into Tool holder complete then push 1R388 in vise with the access holes on Tool holder complete parallel to Vise. (Fig. 16) O-ring case A/ B is moved toward the top of Tool holder complete, and therefore, Ring spring 28 can be relieved from O-ring case A/ B. (2) When the end gap of Ring spring 28 is in the access hole, slide it with slotted screwdriver until it is completely hidden. (3) Using slotted screwdriver, tap Ring spring 28 through the two access holes alternately to push it out of the inner groove of Tool holder complete. (4) The components are removed by tapping with phillips screwdriver and plastic hammer from bit installation side of Tool holder complete. (Fig. 17)
