What causes excessive leakage around the hydraulic motor piston rod wiper on Graco Construction Equipment?
Excessive leakage around the hydraulic motor piston rod wiper indicates a worn or damaged piston rod seal. Replace the hydraulic motor piston rod wiper and seal.
How to fix a Graco LineLazer V 250DC when the engine will not crank?
If your Graco Construction Equipment engine won't crank, the battery might be discharged. Try turning the key switch to ON, choking the engine, and pulling the recoil starter rope. If that doesn't work, the key switch itself could be defective and need replacement. Another possibility is a defective main wire harness, which would also require replacement.
What to do if my Graco LineLazer V 250DC machine will not drive?
If your Graco Construction Equipment isn't driving, first, ensure the engine clutch switch is ON. Check that the hydrostatic drive bypass valve is closed to engage the drive. Also, verify the hydraulic fluid level and add fluid if low. Inspect the drive cable and clutch wire harness for disconnections or breaks, reconnecting or replacing as needed. Other potential issues include a malfunctioning clutch (replace if necessary), a worn or broken ground drive belt (adjust or replace), a faulty ground drive pump (replace), or worn/non-working wheel motor(s) (replace).
Why is fluid spitting from the gun of my Graco LineLazer V 250DC Construction Equipment?
If fluid is spitting from the gun, it could be due to air in the pump or hose. Check and tighten all fluid connections and reprime the pump. A partially clogged tip can also cause spitting, so clear the tip. Lastly, ensure the fluid supply is adequate; refill if low or empty, and prime the pump. Regularly check the fluid supply to prevent the pump from running dry.
Why does my Graco LineLazer V 250DC engine crank slowly?
If your Graco Construction Equipment engine cranks slowly, it might be due to excessive hydraulic load. Ensure the engine clutch switch is turned OFF.
Why isn't the gallon counter adding fluid volume on my Graco LineLazer V 250DC?
The gallon counter may not add fluid volume if the fluid pressure isn't high enough; it must be over 800 psi (55 bar) for the counter to function. Check the pump counter wire for breaks or disconnections. A missing or damaged magnet on the pump could also be the problem. Finally, the sensor itself may be bad and need replacement.
What to do if the display on my Graco Construction Equipment does not turn on?
If the display doesn't turn on, first ensure the key switch is in the ON position. If it still doesn't turn on, the main fuse may be blown and need replacement. Another possibility is a disconnected or damaged cable between the display and main board, which would need reconnection or replacement. Finally, the display board itself may have failed, requiring replacement.
What to do if pressure control knob rotates freely with no pressure change in Graco Construction Equipment?
If the pressure control knob rotates freely without changing the pressure, the set screw at the hydraulic pump connection may be loose. Alternatively, the remote cable could be broken or disconnected, requiring replacement or reconnection.
Why isn't the distance adding properly on my Graco LineLazer V 250DC?
If the distance isn't adding properly, and MEASURE mode is inaccurate, the machine may not be calibrated correctly. Perform the calibration procedure. Also, ensure the rear tire pressure is properly adjusted to 55 +/- 5 psi (380 +/- 34 kPa). Check for missing or damaged gear teeth on the right side (when standing on the platform) and replace the distance gear/wheel hub if needed. Finally, inspect the distance sensor for looseness or damage, and reconnect or replace it as necessary.
Why is the stall or run pressure low on my Graco LineLazer V 250DC Construction Equipment display?
A low stall or run pressure on the display might be due to a pressure setting that is too low; turn the pressure adjusting knob clockwise to increase the pressure. If you have a new pump or new packings, keep in mind that the pump break-in period can take up to 100 gallons of material. A faulty transducer could also be the cause, requiring replacement.
