Why are my JLG Boom Lifts overheating?
Your JLG Boom Lifts may be overheating due to several reasons: * The oil level might be insufficient; in this case, check the oil level and refill if necessary. * The hydraulic oil could be too warm; verify the hydraulic circuit. * The brake may not be fully released; check the brake release pressure.
What to do if JLG Boom Lifts have external oil leakage?
If your JLG Boom Lifts are experiencing external oil leakage, the issue could stem from: * A damaged lifetime seal, O-ring seal, or plug seal. If any of these seals are damaged, replace them. * Loose plugs or screws. Tighten the plugs/screws to resolve this.
Why is there too much noise coming from my JLG 1350SJP?
Excessive noise from your JLG Boom Lifts can be attributed to: * A malfunctioning hydraulic circuit; verify the hydraulic circuit. * Internal damage; check the gearbox.
What to do if JLG Boom Lifts have insufficient braking torque?
If your JLG Boom Lifts exhibit insufficient braking torque, consider the following: * Worn brake discs; replace the brake disc pack. * Damaged parts; check the brake components.
Why is my JLG Boom Lifts overheating?
Overheating in JLG Boom Lifts can occur due to several reasons: * The oil level might be insufficient, in which case you should check the oil level and refill if necessary. * The hydraulic oil may be too warm, requiring a check of the hydraulic circuit. * The brake might not be fully released, so verify the brake release pressure.
Why is there insufficient braking torque in my JLG Boom Lifts?
Insufficient braking torque in JLG Boom Lifts can be caused by: 1. Worn brake discs, which would require replacing the brake disc pack. 2. Damaged brake components, which would need inspection and potential replacement.
How to fix external oil leakage from the plugs in JLG 1350SJP Boom Lifts?
If you notice external oil leakage from the plugs in your JLG Boom Lifts, it might be due to a damaged plug seal, in which case you should replace the plug seal. Alternatively, the plugs or screws might be loose, requiring you to tighten them.
Why is there too much hydraulic noise in JLG Boom Lifts?
Excessive hydraulic noise during the slowing down of the motor speed in your JLG Boom Lifts suggests a malfunctioning hydraulic circuit. You should verify the hydraulic circuit to address this issue.
How to repair external oil leakage from the end cover of JLG Boom Lifts?
If there's external oil leakage from the end cover of your JLG Boom Lifts, it's likely due to a damaged O-ring seal. Replace the O-ring seals to resolve this issue.
What causes noise inside the gearmotor of JLG 1350SJP Boom Lifts?
Excessive noise inside the gearmotor of your JLG Boom Lifts may indicate internal damage. Check the gearbox to identify and address any issues.
