Frequently Asked Questions - HH42 HUSQVARNA

How do I start the Husqvarna HH42 pressure washer?
Ensure the water supply is connected and turned on. Level the product. Position yourself to avoid kickback, then start the engine according to the engine operator's manual. Always wear safety goggles and protective clothing.
What type of detergent can I use?
Only use detergents specifically marketed for pressure washers. Follow the chemical manufacturer's instructions. Never use acids or flammable liquids. Use the black low-pressure spray tip to apply detergent.
Why is my pressure washer not building pressure?
Possible causes: a low-pressure spray tip is installed (use a high-pressure tip), the pressure control knob is set too low, inadequate water supply, clogged inlet screen, obstructed spray tip, or leaking connections. Check and resolve accordingly.
How do I maintain the pump?
Change pump oil every 50 hours of use. Use SAE 30 weight oil (approximately 10 oz). Also, lubricate O-rings regularly and use Pump Saver during storage to protect against mineral deposits and freezing.
Can I use an extension cord?
This pressure washer is engine-driven and does not require an electrical outlet for the pump. However, the engine has a recoil starter. No extension cord is needed.
What safety precautions should I take?
Always operate outdoors away from windows, doors, and vents to avoid carbon monoxide poisoning. Wear safety goggles and protective clothing. Never point the spray at people or pets. The spray gun traps high pressure even after shutdown - always relieve pressure by squeezing the trigger after turning off the engine.
How do I store the pressure washer?
Flush detergent from the system, treat or drain fuel, and protect the pump with Pump Saver or RV antifreeze. Store in a clean, dry area. Do not place a cover on a hot machine.
What is the warranty period?
For consumer use: 24 months on equipment, 36 months on the frame, and 24 months on the engine (Briggs & Stratton). For commercial use: 3 months on all components. Proof of purchase is required.
Can I repair the high-pressure hose?
No. If the hose is damaged and exposing the inner mesh, it must be replaced immediately. Do not attempt to repair it with sealant. Use genuine parts for replacement.
How do I clean a clogged spray tip?
After shutting down the engine and relieving pressure, remove the spray tip from the wand. Use a paper clip or similar tool to dislodge any debris from the tip orifice.

Operation

Step 1: Safe Location

Before starting the pressure washer, there are two equally important safety concerns regarding carbon monoxide poisoning and fire that must be addressed.

Operation Location to Reduce the Risk of Carbon Monoxide Poisoning

The engine exhaust of all fossil fuel burning equipment, such as a pressure washer, contains carbon monoxide, a poisonous gas that could kill you in minutes. You cannot smell it, see it, or taste it. Even if you do not smell exhaust fumes, you could still be exposed to carbon monoxide gas.

By law, it is required in many states to have a carbon monoxide alarm in operating condition in your home. A carbon monoxide alarm is an electronic device that detects hazardous levels of carbon monoxide. When there is a buildup of carbon monoxide, the alarm will alert the occupants by flashing a visual indicator light and an alarm. Smoke alarms cannot detect carbon monoxide gas.

Carbon monoxide alarm

HUSQVARNA HH42 - Operation Location to Reduce the Risk of Carbon Monoxide Poisoning - 2

WARNING! Engine exhaust contains carbon monoxide, a poisonous gas that could kill you in minutes. You cannot smell it, see it, or taste it.

Even if you do not smell exhaust fumes, you could still be exposed to carbon monoxide gas.

  • Operate this product only outdoors, far away from windows, doors and vents to reduce the risk of carbon monoxide gas accumulating and the potential of being drawn towards occupied spaces.
  • Install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms with battery back-up according to the manufacturer's instructions. Smoke alarms cannot detect carbon monoxide gas.
  • Do not run this product inside homes, garages, basements, crawlspaces, sheds, or other partially-enclosed spaces even if using fans or opening doors and windows for ventilation. Carbon monoxide can quickly build up in these spaces and can linger for hours, even after this product has shut off.
  • Point exhaust away from all homes and occupied spaces.
  • If you start to feel sick, dizzy, or weak while using this product, get to fresh air right away. See a doctor. You may have carbon monoxide poisoning.

USE OUTDOORS - AVOID CARBON MONOXIDE POISONING CARBON MONOXIDE ALARM(S) Install carbon monoxide alarms inside your home. Without working carbon monoxide alarms, you may not realize you are getting sick and dying from carbon monoxide poisoning.

Operation Location to Reduce the Risk of Fire

ABOUT YOUR WARRANTY

Warranty service is available only through Briggs & Stratton Authorized Service Dealers. This warranty covers only defects in materials or workmanship. It does not cover damage caused by improper use or abuse, improper maintenance or repair, normal wear and tear, or stale or unapproved fuel.

Improper Use and Abuse - The proper, intended use of this product is described in the Operator's Manual. Using the product in a way not described in the Operator's Manual or using the product after it has been damaged will not be covered under this warranty. Warranty coverage will also not be provided if the serial number on the product has been removed or the product has been altered or modified in any way, or if the product has evidence of abuse such as impact damage or water/chemical corrosion damage.

Improper Maintenance or Repair - This product must be maintained according to the procedures and schedules provided in the Operator's Manual, and serviced or repaired using genuine Briggs & Stratton parts or equivalent. Damage caused by lack of maintenance or use of non-original parts is not covered by warranty.

Normal Wear and Tear - Like most mechanical devices, your unit is subject to wear even when properly maintained. This warranty does not cover repairs when normal use has exhausted the life of a part or the equipment. Maintenance and wear items such as filters, belts, cutting blades, and brake pads (except engine brake pads) are not covered by warranty due to wear characteristics alone, unless the cause is due to defects in material or workmanship.

Stale or Unapproved Fuel - In order to function correctly, this product requires fresh fuel that conforms to the criteria specified in the Operator's Manual. Engine or equipment damage caused by stale fuel or the use of unapproved fuels (such as E15 or E85 ethanol blends) is not covered by warranty.

Other Exclusions - This warranty excludes damage due to accident, abuse, modifications, alterations, improper servicing, freezing or chemical deterioration.

Attachments or accessories that were not originally packaged with the product are also excluded. There is no warranty coverage on equipment used for primary power in place of utility power or on equipment used in life support applications. This warranty does not include used, reconditioned, second-hand, or demonstration equipment or engines. This warranty also excludes failures due to acts of God and other force majeure events beyond the manufacturer's control.
