the mode, inserting Drill bit or adjusting Guide Rod.

Forward /Reversing

Speed Control Switch

 Hold the drill machine with both hands while drilling

 Put forward the left leg ( for a Right handed Person ) with the right index finger on Speed

Control Switch, Hold the handle with Left Hand – vice versa for Left Handed person

 Hold the Drill Machine Horizontally & Drill hole

perpendicular to the Wall

 Slowly increase the speed by using the speed control switch

scale for Elevation Angle marking

Magnetic Compass

Step 16: Adjust SKEW (approx.) as per Look Angle Chart

For example : If SKEW angel is “- 37.2 degree”

1 Division = 5 Degree

Division marking for LNBF rotation = 37.2 / 5 = 7.4

Align “0” mark of LNBF clamp with approx. 7.4 division (Clockwise) on LNBF.

Adjust approximate SKEW as per division marking available on LNBF

Clock wise rotation for negative Polarization angle

Rotate LNBF Clock wise from LNBF connector for negative (-) Polarisation angle. Rotate LNBF Anti Clock wise from LNBF connector for Positive (+) Polarisation angle.

 Slightly Rotate sensitivity knob anti-clock wise. The Indicator needle will move lower ( Left ) side  Again align Reflector till indicator needle reaches to maximum signal level ( Right ) side.

Step 17 : Sat Finder Tracking Procedure

 Repeat this process till you get maximum signals. Track the Reflector to a maximum signal level & sensitivity knob to anti-clock direction as much as possible.

 After getting maximum signal, tighten Azimuth & Elevation bolts  Signal should not decreased during & after tightening

Tightening Azimuth bolts Tightening Elevation bolts

 Then fine tune the Skew till indicator needle reaches to maximum Signal level  Rotate sensitivity knob anti-clock wise till some extent

 Again adjust Skew till indicator needle reaches to maximum Signal level

 Repeat this process till you get maximum signals. Adjust the Skew to a maximum signal level & sensitivity knob to anti-clock direction as much as possible

 After getting maximum signal, tighten LNBF clamp screws

 After Peak Tracking Switch OFF the Satellite Box & Remove the Sat Finder Connections

Step 17 : Sat Finder Tracking Procedure (Contd…)
