CONCEPT AND MAIN APPLICATIONS H

Models HS6600/ HS6601 are 165mm (6-1/2") Circular Saws and have been
developed as the successor to the current model 5604R.
Its main features are as follows:
• More compact and lightweight design
• New housing design L
• Compatible with Guide rail
• Single action lever for quick adjustment of cutting depth
Dimensions: mm ( " )
The difference between HS6600 and HS6601 is as follows: Length (L) 296 (11-5/8)
HS6600: Single-finger switch HS6600 230 (9)
HS6601: Two-finger switch Width (W)
HS6601 232 (9-1/8)
Height (H) 243 (9-9/16)

2 Caution

Repair the machine in accordance with “Instruction manual” or “Safety instructions.

Follow the instructions described below in advance before repairing:
· Wear gloves.
· Remove the cutting tool from the unit, and if it is a saw blade, attach the blade cover to the blade.
· In order to avoid wrong reassembly, draw or write down where and how the parts are assembled, and what are the parts.
· It is also recommended to have boxes ready to keep disassembled parts by group.
· Handle the disassembled parts carefully. Clean and wash them properly.
· If some bolts and screws are too tight, use an impact driver.
· Tighten the bolts and the screws to the specified torque.
