OF THIS MANUAL.
OPERATING TIPS
Adjusting The Spray Pattern
1.
You have a choice of four different
color-coded Nozzles (9) giving you
different spray patterns.
2.
0° Nozzle (colored red): This Nozzle delivers a pinpoint stream and is
extremely powerful. It covers a very
small area of cleaning. This Nozzle
should only be used on a surface that
can withstand this high pressure such
as metal or concrete. Do not use on
wood. Do not use to clean vehicles.
For technical questions, please call 1-800-444-3353.
Page 12
3.
4.
15° Nozzle (colored yellow): This
Nozzle delivers a powerful 15 degree
spray pattern for intense cleaning of
small areas. This Nozzle should only
be used on areas that can withstand
the high pressure from this Nozzle.
Do not use to clean vehicles.
40° Nozzle (colored white): This
Nozzle delivers a 40 degree spray
pattern and a less powerful stream
of water. It covers a wide area of
cleaning. This Nozzle should be
used for most general cleaning jobs
and for cleaning vehicles.
5.
Low Pressure Nozzle (colored
black): This Nozzle is used to apply
chemicals or cleaning solutions. It
has the least power stream. Do not
use to clean vehicles.
6.
NOTE: Before using the Pressure
Washer to clean patio paving slabs, it
is advisable to test a small area first.
Some paving slabs are manufactured
from inferior materials and the use of
a Pressure Washer could damage the
surface.
Using the Detergent Hose
1.
Fill a suitable container with pressure
washer detergent. Always follow
instructions as outlined in the
detergent manufacturer’s manual.
2.
Most automobile detergents are a
combination of a detergent and a
wax solution. These tend to be a
thick viscous liquid. The viscosity
(thickness) of the detergent will
increase in cold weather. It is
recommended that this type of
detergent is diluted with warm water
before filling the container. As a
general guide, a recommended
SKU 97005
dilution rate is 50/50. However, a trial
and error process would determine
the ideal dilution rate for a particular
detergent.
3.
A thick, viscous detergent will not flow
freely from the detergent container
and the residue will cause blockage
in the detergent flow system.
4.
After using a detergent the entire
Pressure Washer system should be
thoroughly flushed out with ample
amounts of water.
5.
If at any time the flow rate decreases,
sputters, or is inconsistent, release
the Trigger of the Spray Gun (6)
and turn off the Engine. Squeeze
the Trigger to release any pressure.
Then check the Nozzle (9) of the
Spray Gun for any blockage. If
blockage is suspected, clean the
Nozzle thoroughly. If the problem still
exists, check and clean the Filter on
the Detergent Hose.
Cleaning Recommendations
1.
Clean an inconspicuous test area
to help avoid damaging the surface.
Always begin with the fan spray at
a distance of about 3-5 feet from
the surface being cleaned to avoid
damaging the surface of the object.
Make sure the test area is clear of
people and water-prone delicate
objects. If a pressure washer
detergent is to be used, apply the
detergent to this area as well. After
cleaning this area, turn off the Engine
and inspect the area carefully for
any damage or discoloration. If any
damage is noted from the Nozzle
used, use a less powerful Nozzle
when cleaning the rest of the area.
For technical questions, please call 1-800-444-3353.
Page 13
If damage or discoloration is noted
from the detergent, do not use the
detergent when cleaning.
2.
First, pass over the area with a light
cleaning. Then clean the area more
thoroughly.
3.
For a vertical or sloped surface:
project, go over the edges of the
streaks with a wide fan pattern to
help blend these lighter areas in.
7.
If several different surfaces are to be
cleaned, make sure not to damage
any of the less solid surfaces while
attempting to clean the harder ones.
This is especially a concern when
cleaning tile and grout, bricks and
mortar, or stones and mortar.
8.
If wood is being cleaned, make
sure not to damage it. Pressure
washed wood will usually require
resurfacing (sanding) and re-coating
with a surface protectant (wood,
stain, varnish) after it has dried. Try
to avoid leaving water on a wooden
surface, as doing so can harm the
surface.
• Wash from the top down.
• If possible, direct the stream of
water in the same direction as the
slope towards a drainage area.
This will enable better drainage
and, therefore, better cleaning.
4.
For a flat surface:
• If a thin layer of water accumulates on the surface, periodically
use a stream of water to direct the
water toward the drainage.
• After the major cleaning is done,
sweep the surface with the stream
of water to help direct loose debris
toward the drainage.
5.
If detergent is to be applied, use only
pressure washing detergent. Other
detergents may clog or damage the
Pressure Washer. Apply the detergent at low pressure. Allow the detergent several minutes to sit and soak
into the work surface. This will improve cleaning efficiency. Make sure
to rinse off all detergent completely.
6.
Hold the Spray Gun (6) at about a
45° angle and steadily sweep the
water stream back and forth. If a
severe, head-on angle is used, dirt
may imbed in the surface being
cleaned. Follow a steady, consistent
pace during cleaning. This will help
prevent stripes or discoloration
afterwards. If streaking or uneven
cleaning is noted at the end of a

days from the date of purchase. This warranty does not apply to
damage due directly or indirectly, to misuse, abuse, negligence
or accidents, repairs or alterations outside our facilities, criminal
activity, improper installation, normal wear and tear, or to lack of
maintenance. We shall in no event be liable for death, injuries
to persons or property, or for incidental, contingent, special or
consequential damages arising from the use of our product.
Some states do not allow the exclusion or limitation of incidental
or consequential damages, so the above limitation of exclusion
may not apply to you. This warranty is expressly in lieu of all
other warranties, express or implied, including the warranties of
merchantability and fitness.
To take advantage of this warranty, the product or
part must be returned to us with transportation charges prepaid.
Proof of purchase date and an explanation of the complaint must

first retail purchaser.
2. No Charge Repair or Replacement
Repair or replacement of any warranted part will be performed
at no charge to the owner if the work is performed through a
warranty station authorized by HFT. For emissions warranty
service, contact the HFT Customer Service Department at
1-800-444-3353.
3.Consequential Damages Coverage
Coverage under this warranty shall also extend to the failure
of any engine components caused by the failure of any
warranted part while it is still covered under this warranty.
Your emission control system may include parts such as the
carburetor or fuel-injection system, and the ignition system. Also
included may be hoses, belts, connectors and other emissionrelated assemblies.
Where a warrantable condition exists, HFT will repair your
engine at no cost to you including diagnosis, parts and labor.
