The following is to be used as a general guide for tire inflation. Check the
sidewall of the tire for recommended inflation. It is important that tires are
inspected after unit is loaded. Do not exceed maximum recommended tire
pressure.
Wheel Torque Specification
Tire Pressure Table
It is an extremely important safety procedure to apply and
maintain proper wheel mounting torque on your trailer axle.
Torque wrenches are the best method to assure the proper
amount of torque is being applied to a fastener.
Wheel lugs should be torqued before first road use and after
each wheel removal. Check and re torque after the first 10
miles, 25 miles, and again at 50 miles. Check periodically
thereafter.
Note: Wheel lugs must be applied and maintained at the
proper torque levels to prevent loose wheels, broken studs,
and possible dangerous separation of wheels from your axle.
1. Start all lugs by hand to prevent cross threading.
2. Tighten lugs in sequence, as shown in the diagram.
3. Tighten the lugs - see chart

Speed Identification Symbol (SIS)
The SIS and standard is part of the US Federal Regulation 49CFR Part 562.
The purpose of the Speed Identification Symbol (SIS) standard is primarily to identify equipment that has been specifically
designed for ground speeds greater than 40 km/h (25 mile/h) but under 65 km/h (40 mile/h), when operating or traveling
on public roads.
The SIS also identifies the farm machineries’ maximum safe travel speed. Maximum rated safe travel speed of Horst
Header Wagons is 30 mile/h.
The SIS needs to be used in conjunction with the SMV sign.
California Proposition 65
You may see a warning label similar to the following:
WARNING
Cancer and Reproductive Harm
www.P65 Warnings.ca.gov
This warning is required by California Proposition 65 (Prop 65), which is meant to notify California residents of exposures
to Prop 65-listed chemicals. For more information go to ‘www.P65Warnings.ca.gov.’
