Work Area Safety

 Keep work area clean and well lighted. Cluttered or dark areas invite accidents. Use the LED

light work light on the Model TL-900 (shown in Fig. 1) whenever possible to reduce injuries.

 Do not operate the Model TL-900 in explosive atmospheres, such as in the presence of

flammable liquids, gases or dust. Although the Model 900 incorporates safety measures that

enclose sparks, its exterior metal parts may create sparks that can ignite flammable materials.

 Keep bystanders, children and visitors away while operating the Model TL-900. Distractions

can cause you to lose control.

 Make sure vehicles are braked, chocked and stable.
 Use extreme caution when working on or around a vehicle on a jack.

Electrical Safety

 The Anderson quick connector ( shown in Fig. 1) on your Model TL-900 must match another
Anderson quick connector. Mismatched connectors create the risk of electrical shorting.
 Make sure the cables, switches and power connector are in good working order
before making a secure connection. Damaged cables, plug, switches or receptacles will reduce
the amount of power available to the tool and potentially cause damage to it or the vehicle.

 Do not immerse the Model TL-900 in standing water.
 Do not abuse the power cables. Never use the cord for carrying, pulling or unplugging the

tool. Keep the cables away from sharp edges and moving parts.

 Make sure the power cables are free from snags and tangles before operating the tool sys-

tem.

Personal Safety

 Always stay alert and use common sense when operating the Model TL-900. Never operate

the tool while tired or under the influence of drugs, alcohol or medication. The Model TL-900

is a very powerful tool that can cause serious personal injury and property damage if not properly
used.

 Use safety equipment. Always wear eye and ear protection. Safety equipment such as dust

masks, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will
reduce personal injuries.

 Avoid accidental start up of the Model TL-900 by applying power only when ready to use. Un-

plug immediately when work is completed. Keep the trigger free from obstructions.

 Make sure any attachments such as sockets, adapters and torque extensions are secured to

the tool’s square drive prior to operating the Model TL-900.

 Do not overreach. Keep proper footing and balance at all times. Make sure cables are free

from snags and tangles when using the Model TL-900 off the ground.

 Dress properly. Do not wear loose fitting clothing or jewelry. Make sure hair, clothing and

gloves are away from moving parts.

 Keep your Model TL-900 handle clean from oil and grease. Holding a slippery handle will

make it difficult to safely control this powerful tool.

Tool Use And Care

 Operate the Model TL-900 in 1 - 2 second long bursts. If the tool does not loosen the fastener

(nut or bolt) after (3) 1 – 2 second bursts STOP and use other means to loosen the fastener.

 Use only impact “rated” sockets. Non-impact sockets can break and cause
personal injury or property damage.

 Always finger tighten fasteners before securing with the Model TL-900 to avoid cross-

threading.

 Make certain that impact sockets are securely seated over the fastener prior to tightening or

loosening a bolt or nut.

 Always use the correct size impact socket size. Incorrect sockets can damage the fastener or

slip off causing injury.

 Always clean your Model TL-900 and all electrical connectors after use.

Operating Instructions

 Hold the Model TL-900 firmly using both hands while operating it. Always wear safety gog-

gles or other approved eye protection. Heavy impacting can cause flying debris that can cause
permanent eye damage.

 Sockets and fasteners can get hot during operation. Use protective gloves when handling them.
 Do not operate the Model TL-900 for long periods of time. Vibration caused by the tool’s impact-

ing action may be harmful to your hands and arms. Use thick gloves to provide extra cushion and
limit exposure by taking frequent rest periods.

Operating Voltage

Your Model TL-900 requires a source of 24-30 VDC that is capable of providing 100 AMPS
(intermittent) to generate optimum impacting strength.

If you have a solid source of 24-30 VDC applied to your Model TL-900 and the impacting strength of the
tool seems sluggish or weak, please contact DC-Matic to obtain a return authorization (RMA) so we can
expedite the repair or replacement of your tool or arrange to have a new set of motor brushes sent to
you.

Thermal Protection/Cut Off

Your Model TL-900 is equipped with an internal, bi-metal thermostat that will shut-down the tool (kill the
trigger switch) when the tool becomes over-heated. Testing has revealed that this tool’s thermal
protection circuit will not activate if the Model TL-900 is used intermittently and allowed an adequate
amount of cool-down time between uses.

Note: When used in an ambient temperature of 90 degrees F the average amount of time needed for
the thermal protection circuit to re-set time is (30) minutes.

Control Box

Your Model TL-900 is equipped with a forward-positioned, 12-cluster LED work light (shown in Fig. 1).
The work light’s On/Off switch is located on the control box (shown in Fig. 3). To achieve the highest
degree of workplace safety always turn ON the work light when operating the Model TL-900 in a low or
no-light environment. The control box is “Factory Sealed” and must remain that way. Unauthorized

opening of the control box will void the tool’s warranty.
