2.0 IMPORTANT INFORMATION
2.1 ABOUT THIS MANUAL
The purpose of this manual is to assist you in properly and safely operating and maintaining the
135lb Stainless Steel Spreader. Read and understand this entire manual before attempting to set-
up, operate, adjust, perform maintenance on, or store this attachment. This manual provides
essential information and instructions, which will help you enjoy years of dependable
performance.
The designed and tested safety of the 135lb Stainless Steel Spreader is dependent upon its
operations within the parameters and limitations explained in this manual. Be familiar with and
follow all safety rules in this manual as well all safety rules for any related equipment, including
the Snowrator.
Although these instructions have been complied through extensive field experience and
engineering data, some information presented herein may be generated in the nature due to
unknown and/or varying operating conditions. However, these instructions, combined with your
increased experience with the Snowrator, will enable you to develop procedures suitable to your
particular application.
The illustrations and data used in the manual were current at the time of printing, but the
Snowrator and 135lb Stainless Steel Spreader may vary slightly due to ongoing engineering
changes. L. T. Rich Products, Inc reserves the right to implement engineering and design
changes to the Snowrator as may be necessary without prior notification.
2.2 OVERVIEW
The 135lb Stainless Steel Spreader is an optional attachment that can be mounted to the
Snowrator and used to spread salt/granular product. It has a variable speed electric motor which
allows variable spread distances from 6 to 25 feet. This depends on volume/density, particle size
and rate of travel, and weather conditions. The pattern can be increased or decreased while
spreading depending on needs. Travel at a constant speed for consistent results.
The 135lb Stainless Steel Spreader Attachment features stainless steel construction, electronic
speed control, vibrator, rate control and directional control.
2.3 SAFETY
Safety is a primary concern in the design and manufacturing of all L. T. Rich Products.
Unfortunately, our extensive efforts to provide safe equipment can be negated by a single
careless act of an operator. In addition to the design and configuration of the 135lb Stainless
Steel Spreader, hazard control and accident prevention are also dependent upon the awareness,
condition, maintenance, and storage of the Snowrator and all optional attachments. This section
is only for the 135lb. Stainless Steel Spreader. Please refer to the Owner's Manual for applicable
safety information for the Snowrator. Additional safety tips are provided throughout this
document.

5.0 OPERATION
5.1 OPERATIONAL CONTROLS
The 135lb Stainless Steel Spreader has four controls. These are the Vibrator Switch, Spinner
Switch, Spinner Speed Control, and Hopper Cable. These controls can be operated while the
spreader is in use.
5.1.1 AUX Control Panel
The Hopper Cable is located to the left of the Vibrator Switch. This Cable opens the Hopper
Door when pulled upward and closes the Hopper Door when pushed downward. The Hopper
Cable will only open as far as the Rate Control setting will allow.
The Vibrator Switch is located to the right of the Hopper Cable. It has a built-in light that
indicates when it is on. Pressing the top of the switch will turn on the Vibrator mounted behind
the Hopper. Pressing the bottom will turn it off.

Operational Controls Cont…
5.1.2 Main Control Panel
The Main Control Panel is where the Speed Control Unit for the Spinner Motor is located. The
unit has an ON/OFF button, speed adjustment controls and an LED indicator strip. The LED
indicators alert the operator of malfunctions when they flash in specific patterns. See the
troubleshooting section for more information.
Power is applied to or removed from the unit by pressing the ON/OFF button. Speed Control is
adjusted via the TURTLE and RABBIT buttons on the Speed Control Unit. Pressing the
TURTLE button reduces Spinner speed and pressing the RABBIT button increases it. See
section 5.2.2.
In extreme cold the grease in the spinner motor gearbox may cause the controller to error out due
to too high of a current draw. The controller has a cold start sequence that will warm the motor
up and allow the user to run the spreader normally in these conditions. If at any time you need to
exit the COLD START SEQUENCE press the OFF button. The next time the controller is
started it will be in normal operating mode.
1. Close the feed gate to prevent material loss.
2. Turn off the spreader
3. Check to make sure there are no obstructions around the spinner disk.
4. To activate the COLD START SEQUENCE, press and hold the turtle and rabbit then
press the power button and release all three. The LED lights will scroll across the
controller from left to right letting you know the COLD START SEQUENCE is
activated.
5. During the COLD START SEQUENCE the motor will ramp up to full speed and stay
there until the amp draw decreases to a specific limit. Then the controller will drop the
speed down to half speed until the amp draw decreases to a specific limit. Then the
controller will drop the speed down to the lowest setting until the amp draw decreases to
a specific limit. Once the controller senses the current is within range the controller will
exit the COLD START SEQUENCE. The LED lights will stop scrolling and only the
first light will remain on.
6. The controller is now out of the COLD START SEQUENCE and can be operated
normally.
