(5) Dust- and water-resistant triple-sealing construction <patent pending>
The Model CR 13VA has a triple-sealing construction to protect from the large amount of dust generated when
cutting construction materials, autoclaved lightweight concrete, etc. and also from waste water when cutting
pipes.
Dust-resistant felt ring (with backup ring)
It prevents dust from entering by way of the plunger (reciprocating shaft).
Dust- and water-resistant seal ring (made of heat-resistant rubber)
It prevents dust and waste water from entering by way of the plunger (reciprocating shaft).
Dust- and water-resistant seal sleeve (made of heat-resistant rubber)
It prevents dust and waste water from entering through the clearance of the gear case.

(6) Sturdy and heat-resistant thanks to the double-molded front cover (rubber and plastic) <patent pending>
Front covers made of rubber have been generally used for saber saws. However, such front covers are not so
durable and there is increasing demand for a sturdier saber saw. To cope with this demand, the Model
CR 13VA is equipped with a durable double-molded front cover that is composed of a glass-fiber reinforced
polycarbonate body and a nonskid rubber grip. In addition, heat resistance is improved by making a clearance
between the front cover and the gear case to flow cooling air for the motor.
