10. Disposal

Most of the materials from which Hilti electric tools are manufactured can be recycled. The materials must be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for taking back your old electric tools for recycling. Please ask your Hilti customer service department or Hilti representa- tive for further information.

Should you wish to return the electric tool yourself to a disposal facility for recycling, proceed as follows: Dismantle the electric tool as far as possible without the need for special tools. Use absorbent paper to wipe oily parts clean and to collect any grease that runs out (total quantity approx. 50 ml). This paper should also be disposed of correctly. On no account should oil or grease be allowed to enter the waste water system or to find its way into the ground.

The individual parts should be separated as follows:

Hilti offers a range of advanced cordless reciprocating saws, including the WSR900, WSR1400-PE, WSR900-PE, and WSR1250-PE, each designed for professionals in construction and industrial sectors. These tools combine high-performance power with innovative technologies to meet the demanding needs of users.

The Hilti WSR900 is a lightweight and compact reciprocating saw, making it ideal for tight spaces or overhead applications. It features a brushless motor for increased efficiency and longer lifespan, providing consistent cutting power. The saw is designed with a tool-free blade change system, allowing users to switch blades quickly and easily, which enhances productivity on the job site. Additionally, the WSR900 offers an adjustable speed control feature that enables users to tailor the cutting speed to the material being worked on, from wood to metal.

The WSR1400-PE is a step up, featuring a more powerful 1,400-watt motor. This model is particularly effective for heavy-duty applications, such as demolition work or cutting through thick materials. It offers precise blade control with its integrated electronic speed control, allowing for versatility with different materials. This saw is ergonomically designed for comfort during extended use, reducing user fatigue.

On the other hand, the WSR900-PE combines the compactness of the WSR900 with the robust features of the PE line. It is equipped with an energy-efficient motor and features an integrated LED light to illuminate the cutting area, enhancing visibility in dim conditions. The WSR900-PE also includes vibration dampening technology which minimizes user fatigue and improves cutting accuracy.

Lastly, the WSR1250-PE offers the most power in the lineup at 1,250 watts, making it suited for the toughest applications. It features a dual speed setting that allows users to switch between fast cutting and precision cutting modes. This saw also incorporates Hilti's patented dust extraction system, which helps maintain a clean work environment and improves visibility. Its robust design ensures durability under rigorous working conditions.

In conclusion, the Hilti WSR series of reciprocating saws provides a comprehensive range of options suitable for various applications and user preferences. With features such as brushless motors, tool-free blade changes, ergonomic designs, and advanced dust extraction systems, these tools are engineered to enhance productivity, efficiency, and comfort in demanding work environments.
