1. Introduction

The SKR300 is an automatic visible laser that can be used for levelling, vertical

alignment, plumbing and squaring.

The SKR300 laser has these advanced features:

• Automatic self-levelling in both horizontal and vertical modes

• Choice of beams: rotation plane, scanning, chalk line, single point or constant

squaring

• Square shot that’s left / right adjustable

2. Operation

On / Off Key

Press the On/Off key to switch the laser on or off. It will

start automatic levelling.

Tilt Key

Tilt: H.I. – Alert mode. Will work only when selected. The

Tilt function is also known as the H.I. (Height of

Instrument) Alert. This feature stops the laser

automatically if the laser is jarred or moved. This

function is only available in Automatic mode. Press the

Tilt key after turning the instrument on. The H.I. Alert

feature is ON (H.I. light blink) after the instrument has

self-leveled for 30 seconds.

If the laser is disturbed, the head will stop rotating, laser

beam shut off and the H.I. light will be solid on. You

have to restart the instrument and check the reference.

Works with 3 beams mode (Normal, Chalk Line,

Scanning).

Automatic / Manual Key

SKR300 (version 1-12-03) Page 8

Auto : Automatic levelling.

Default mode when laser is switched on

Man : Manual use.

The SKR300 laser is always in the automatic self-levelling mode (auto) when

turned on. Once the instrument has self-leveled, the laser head will start

rotating.

You can choose to have constant rotation by using the Manual mode. This way, the

beam will rotate even if the instrument is not leveled. The red light above the

Auto / Manual button will blink to indicate the instrument is in manual mode.

SKR300 (version 1-12-03) Page 9

2a. Horizontal Setup

The SKR300 can be used directly on the ground or

mount on a standard tripod (5/8-11).

Press the On/Off key to switch the laser on. It will

start automatic levelling.

To stop the rotation, press once on opposite

direction Left (14) or Right (15).

When the head stop briefly press 14 or 15 to move

the laser beam to a specific point.

You can also manually spot the beam by rotating the

laser head with your hand.

To adjust the rotation speed, press Left (14) or Right

(15) continuously according to the direction you

wish.
