Frequently asked questions
What does the lower blade of the HA 200 do?
The lower blade is fixed to the workbench and supports the sheet metal during cutting, opposite the movable upper blade.
Wear is symmetrical with the upper blade, but the lower blade tends to deform under the weight of the sheet metal during intensive operations. Replace both simultaneously to even out the cutting pressure.
What does the HA 200 work on?
It is a manual angle notcher for angles up to 200 x 200 mm. Manual lever operation with hardened steel blades.
Suitable for metal fabrication shops and blacksmith workshops. Regular replacement of knives maintains cutting quality on angle profiles.
Why a specific set for stainless steel?
Stainless steel knives are made of superior quality hardened steel, with specific heat treatment to withstand the high stresses of cutting stainless steel.
Stainless steel is 1.5-2 times more resistant to cutting than mild steel. Standard knives would wear out quickly. Stainless steel-rated knives have a hardness of 60-65 HRC and resist heating and deformation.
When to replace knives for intensive use?
For continuous use (8 hours/day), a revision is recommended every 6 months and preventive replacement every 12-18 months.
Wear indicators: cutting with burrs, deformation of the sheet edge, altered noise during cutting, excessive effort during operation. Keep a spare set in stock.
How is manual replacement performed?
For manual shears and notchers, replacement can be performed by the operator: removal of fastening screws, disassembly of the old knife, assembly of the new one with the correct tightening torque.
Important: respect the tightening torque indicated in the manual (typically 30-60 Nm). Insufficient tightening causes the knife to move, excessive tightening risks cracking it. Krollit provides technical documentation.
