The following provides approximate
Magnum HD
settings when only the product weight, square foot
coverage, and visual inspection of the material is available.
The conversions should be used as guidelines for establishing proper rate settings for the particular product being applied. Steps for
obtaining the most accurate settings are outlined in the “How to Determine Spreader Settings and Spread Width” section of this manual.
These settings are approximate and may vary due to physical characteristics of the product. Walking speed, wear, condition of the turf
and humidity, may cause actual rate setting to deviate. No expressed nor implied warranty or guarantee is provided as to coverage or
uniformity indicated by these rate settings.
1.
Never store unused material in spreader. Return
unused product to its original container.
2.
Wash spreader thoroughly after each use and dry
completely in sun or heated area.
3.
Grease axle bearings in frame. Oil the impeller shaft
bearing in hopper, pivot points on the shut-off plate
and the spring in the housing behind the rate plate.
4.
Remove gear cover and wash gears thoroughly. Oil
all bearing areas and face of gear teeth. Lubricate gear
teeth with dry graphite. Re-install gear cover.
5.
Gear mesh should be checked on a regular basis
during high use periods. Clearance between the axle
gear and pinion gear should be minimal but not tight. If
adjustment is necessary, loosen axle collar set screw
and hold gears together. Slide axle collar against the
gear support and tighten axle collar set screw. Spin
drive wheel. Gears should run freely and smoothly.
6.
Impeller surface should be cleaned periodically to
remove build-up of product. Build-up can cause the
spread pattern to change.
7.
Tire pressure should be 20-25 PSI.
