Torque Wrench SlimLine (TWSL)

Description: The TWSL torque wrench is a ratchet-type torque tool for tightening nuts and bolts. It

uses interchangeable drive links to fit a variety of sizes. It is powered with a 690 bar (10,000 psi)

hydraulic pump unit; the torque output from the TWSL torque wrench is proportional to the pump

pressure applied.

Safety Symbols and Definitions

The safety signal word designates the degree or level of hazard seriousness.

DANGER: Indicates an imminently hazardous situation which, if not avoided, will result in

death or serious injury.

WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in

death or serious injury.

CAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in

minor or moderate injury.

CAUTION: Used without the safety alert symbol indicates a potentially hazardous situation which, if

not avoided, may result in property damage.

IMPORTANT: Important is used when action or lack of action can cause equipment failure, either

immediately or over a long period of time.

Safety Precautions

WARNING: To prevent personal injury,

The following procedures must be performed by qualified, trained personnel who are

familiar with this equipment. Operators must read and understand all safety precautions

and operating instructions included with the device. If the operator cannot read these

instructions, operating instructions and safety precautions must be read and discussed

in the operators native language.

These products are designed for general use in normal environments. These products

are not designed for use in special work environments such as: explosive, flammable or

corrosive. Only the user can decide the suitability of this product in these conditions or

extreme environments. SPX Bolting Systems will supply information necessary to help

make these decisions. Consult your nearest SPX Bolting Systems facility.

Safety glasses must be worn at all times by the operator and anyone within sight of the

unit. Additional personal protection equipment may include: face shield, goggles,

gloves, apron, hard hat, safety shoes and hearing protection.

The owner of this tool must verify that safety-related decals are installed, maintained

and replaced if they become hard to read.

Shut OFF the motor before opening any connections in the system.

Pump

WARNING: To prevent personal injury,

Do not exceed the hydraulic pressure rating on the pump nameplate or tamper with

the internal high pressure relief valve. Creating pressure beyond rated capacities

can result in personal injury.

Retract the system before adding fluid to prevent overfilling the pump reservoir. An

overfill can cause personal injury due to the excess reservoir pressure created when

cylinders are retracted.
