Simple tips for machine operators

Hydraulic Oil

Oil is the lifeblood of all hydraulic equipment. The simplest thing we can do is “Look at It” it should look clean and be free from contamination, Clean oil free from dirt and moisture will keep your systems trouble free and help prevent breakdowns and downtime.


We cannot stress enough how important Hydraulic filtration is on every hydraulic system, make sure your  systems are filtered and change out your filters to an organised program. For hydraulic systems that are deemed vital to your business inquire about on site and off site oil testing options.

Hydraulic Cylinders

Operating cylinders with bent shafts causes the worst possible damage. If you suspect a bent shaft. Or your cylinder is leaking from the shaft seal, get it repaired and make sure it’s repaired properly.

Here at Jesco we see thousands of cylinders with bent shafts. We are not sure why operators do it but for some reason the first thing they do is to try and retract the shaft. Maybe they think it is magically going to straighten itself but as it retracts and the bend starts entering the head the piston inside the barrel often tilts slightly digging into the inside of the cylinder severely scoring the barrel, at the same time huge pressures build up in the cylinder head  resulting in most cases with the head  splitting or shattering. What started out as a shaft straightening or shaft replacement has suddenly became a total cylinder rebuild or a complete cylinder replacement.

So please, If you bend a shaft immediately STOP what you doing and get it fixed. It could save you thousands.

Hydraulic Pumps and Motors

Pumps and Motors will generally give you some warning of oncoming problems. If you notice an increase in noise levels, excessive heat or a drop in performance get it checked out before it is too late.

Hydraulic Hoses

Avoid letting you hoses get to the stage where they blow out. A large amount of dirt/contamination can be induced into your systems because of hose failure.  When you know you have damaged hoses or a hose in poor condition plan a replacement program it will save you downtime and avoid contamination.


Continually running or frequent cycling of your compressors can rocket up your power bills and are the most obvious signs of problems.
Fill a squeeze bottle with water, add a squirt of dish washing liquid and use this to check out your entire system. Check all joints, fittings, shaft seals, actuators and everything else air is passing through or operating on your system.

Fixing air leaks could save you thousands in power bills plus add years to the life of your compressors.
