Warning

Warning
The following warnings include general safety information for this equipment. Further product specific warnings may be included in the text where applicable.
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:
If using solvent based material, the LineLazer must only be used outside or in buildings very well ventilated with fresh air.
The LineLazer must be separately grounded when being cleaned.
The LineLazer uses special, conductive tires for static grounding. No substitutions are allowed. Use only Graco-supplied replacement wheels and tires.
Do not fill fuel tank while engine is running or hot; shut off engine and let it cool. Fuel is flammable and can ignite or explode if spilled on hot surface.
When flammable liquid is sprayed or used for flushing or cleaning, keep sprayer at least 20 feet (6 m) away from explosive vapors.
Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).
Keep work area free of debris, including solvent, rags and gasoline.
Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes are present.
Ground equipment and conductive objects in work area. See Grounding instructions.
Use only grounded hoses.
Hold gun firmly to side of grounded pail when triggering into pail.
If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
Do not point gun at anyone or at any part of the body.
Do not put your hand over the spray tip.
Do not stop or deflect leaks with your hand, body, glove, or rag.
Do not spray without tip guard and trigger guard installed.
Engage trigger lock when not spraying.
Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.
PRESSURIZED EQUIPMENT HAZARD
Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.
Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.
Tighten all fluid connections before operating the equipment.
Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
MOVING PARTS HAZARD
Moving parts can pinch or amputate fingers and other body parts.
Keep clear of moving parts.
Do not operate equipment with protective guards or covers removed.
Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.

Warning
WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings.
Check equipment daily. Repair or replace worn or damaged parts immediately.
Do not alter or modify equipment.
Use equipment only for its intended purpose. Call your Graco distributor for information.
Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
Do not use hoses to pull equipment.
Keep children and animals away from work area.
Comply with all applicable safety regulations.
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical reaction and equipment rupture, and result in death, serious injury, and property damage.
SUCTION HAZARD
Never place hands near the pump fluid inlet when pump is operating or pressurized. Powerful suction could cause serious injury.
CARBON MONOXIDE HAZARD
Exhaust contains poisonous carbon monoxide, which is colorless and odorless. Breathing carbon mon­oxide can cause death. Do not operate in an enclosed area.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.
Read MSDS’s to know the specific hazards of the fluids you are using.
Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:
Protective eyewear
Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
Hearing protection
RECOIL HAZARD
Brace yourself; gun may recoil when triggered and cause you to fall, which could cause serious injury.

Pressure Relief Procedure
WARNING
Read Injection Hazard, page 3; Burn Hazard, page 4
1. Lock gun trigger safety.
2. Turn engine ON/OFF switch to OFF.
3. Move pump switch to OFF and turn pressure control knob fully counterclockwise.
4. Unlock trigger safety. Hold metal part of gun firmly to side of grounded metal pail, and trigger gun to relieve pressure.
5. Lock gun trigger safety.
6. Open pressure drain valve. Leave valve open until ready to spray again.
If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen
tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Now clear tip or hose.
CAUTION
For detailed engine maintenance and specifications, refer to separate Honda Engines Owner's Manual, supplied.
AFTER THE FIRST 20 HOURS OF OPERATION:
Drain engine oil and refill with clean oil. Reference Honda Engines Owner's Manual for correct oil viscosity.
WEEKLY: Remove engine air filter cover and clean ele­ment. Replace element, if necessary. If operating in an unusually dusty environment: check filter daily and replace, if necessary.
Replacement elements can be purchased from your local HONDA dealer.
AFTER EACH 100 HOURS OF OPERATION:
Change engine oil. Reference Honda Engines Owner's Manual for correct oil viscosity.
SPARK PLUG: Use only BPR6ES (NGK) or W20EPR-U (NIPPONDENSO) plug. Gap plug to 0.028 to 0.031 in. (0.7 to 0.8 mm). Use spark plug wrench when installing and removing plug.
Front Wheel Alignment:
Align front wheel as follows:
1. Fig. Loosen cap screw (90).
DAILY: Check engine oil level and fill as necessary.
DAILY: Check hose for wear and damage.
DAILY: Check gun safety for proper operation.
DAILY: Check pressure drain valve for proper operation.
DAILY: Check and fill the gas tank.
ti6392a

DAILY: Check level of TSL in displacement pump pack­ing nut. Fill nut, if necessary. Keep TSL in nut to help
FIG. 1
prevent fluid buildup on piston rod and premature wear of packings and pump corrosion.

If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid.
