During operation
The pressure was set at the factory during the testing procedure; no adjustments to the machine should be required
for operation.
During operation, do not leave the machine running for more than two minutes without the
trigger gun being pulled.
Although your machine has a by-pass valve on it and may have a thermal relief system,
this pressure build-up can cause extensive pump damage. If machine will not be discharging water for more than
two minutes, shut the machine off.

Use extreme caution when attaching devices to the discharge of this equipment. Allow
only trained individuals to operate this machinery. The attachments must be rated to
operate within the pressure range of the equipment or injury could occur. Only use
attachments designed, rated, and sized for the equipment by the manufacturer.
The discharge hoses and fittings should be inspected before every use. Also inspect the connec-
tions made on the hose reels. Refer to accessories listing and exploded views included for speci-
fications and replacement parts.
For pressure wash applications, the ideal hose to deliver adequate water flow and pressure at dis-
tances up to 300 feet is a 3/8” ID hose with a minimum burst pressure rating no less than four
times the operating pressure of the equipment. For drain jetting and sewer cleaning, a hose
should be selected for the adequate pressure range and length needed. The diameter of the hose
should be chosen from the chart below for the application requirements.

-Remember, when selecting a hose, the smaller diameter and longer the hose, the greater the pres-
sure and flow loss will be.
-Do not couple hoses together for drain jetting. The long couplings will get caught in bends in
the drain lines.
-When drain jetting, always attach a shut-off valve, trigger gun, or foot valve directly to the hose
to be inserted in the drain. This ensures safe shut-off of the water flow at the user’s discretion.
In drain jetting applications, the hose must be inserted into the drain line at least five
feet before starting water flow. Be sure machine is not powered on before hose is
inserted into the drain. Be sure machine is shut down before removing the hose from
the drain. Always be sure hose is marked at the point five feet from the nozzle to iden-
tify nozzle position.
Drain and trap hoses listed in the accessory sheet are fitted with a twist-fast coupler. Your drain
jetting equipment is shipped with an assortment of twist-fast couplers to make the necessary con-
nections for the drain hose to be installed either on the existing hose, by removing the drain noz-
zle, or by installing it directly to the foot valve included on some models.
The nozzle, or tip, of the machine is used to restrict the discharge water flow to achieve the rated
operating pressure of the equipment. Only use a properly sized nozzle for your equipment. The
nozzle should be inspected before every use for obstructions and nozzle wear. New nozzles can
be selected from the accessory sheet enclosed in the Operator’s Manual folder pocket.
