adjust tine height

The tine height is pre-adjusted for average lawn and may not need to be changed. Changes can be made to tine height if working conditions require it. Only make adjustments to tine height when Power Rake is turned off and unplugged from a power source. There are 5 positions for the tines (.7", .9", 1.1", 1.4" and 1.7"). Pull adjustment arm out from engagement hole, move it and then let it re-engage in the desired height position. Make adjustments by 1-step increments only and alternate between left and right sides when making adjustments. Adjustment arms must always be same height position when using the machine.
